HomeIn this guide I will explain how to disassemble the display panel and remove LCD screen with inverter board from a HP Pavilion dv9000 series laptop. Do not disassemble your laptop if it’s still under warranty.
You’ll find instructions for removing hard drive, memory, wireless card and keyboard in my previous post.

HP offers free repair for some out of warranty Pavilion dv9000 laptops.
LCD screen and inverter board removal instructions.
First, remove the battery. There are five screw seals located on the LCD screen bezel. Remove all five seals with a sharp object. Remove all five screws found under the seals.
Now we are going to remove the LCD screen bezel. Insert your fingers between the bezel and LCD screen and carefully disengage plastic latches.
Continue removing the bezel.
LCD sceen bezel has been removed.
You’ll find the inverter board under the screen. Carefully unplug cables from both sides of the inverter board. Remove the screen inverter and replace with a new one if needed.
NOTE: some HP Pavilion dv9000 laptops come with dual backlight and require a dual inverter board. Instead of one connector on the right side (as it shown on the picture above), the dual inverter has two connectors.
In the official service manual for HP Pavilion dv9000 I found the following part numbers:
Display inverters:
For use with Dual Lamp display panels 432959-001
For use with Single Lamp display panels 431391-001
Remove three screws from each side of the screen. These screws securing the screen hinges to the cover.
Now you can access the back side of the screen. Carefully remove sticky tape securing the video cable. Unplug the video cable from the screen.
Remove two screws from each side of the LCD screen. These screws securing the screen to the hinges.
Remove the screen and replace it with a new one if needed.
Note: some HP Pavilion dv9000 laptops come with dual backlight LCD screens. On the picture above the single backlight lamp LCD is displayed.
The dual backlight LCD has two backlight cables.
In the official service manual for HP Pavilion dv9000 I found the following part numbers for LCD screens:
Display panels:
17.0-inch, WXGA+, TFT Dual Lamp display panel with BrightView 432954-001
17.0-inch, SXGA+, TFT Single Lamp display panel with BrightView 432953-001
17.0-inch, WXGA+, TFT Single Lamp display panel with BrightView 432952-001
LCD screen, bezel and inverter have been removed.
This model has a known issue – broken left hinge. In the next post I explain how to remove and replace the broken left hinge.
If your HP Pavilion dv9000 notebook has no video at all, it could be related to the video chip failure on the motherboard. Take a look at this video tutorial explaining how to fix failed video chip in HP Pavilion dv9000.

Just wondering if you can tell me where the swich that turns the LCD off when you close the lid of the dv9000 is. Mind is stuck and noe working. Thanks
October 12th, 2008 at 10:49 am
David,
I don’t have this laptop in front of me, but I believe it has magnetic lid close switch. There is a magnet somewhere inside the display panel. When you close the display the magnet activates the lid close switch. Most likely the switch is located on the motherboard but I cannot confirm if this info is 100% correct.
Please correct if I’m wrong.
October 22nd, 2008 at 5:45 am
I can say that there is no magnetic sense at the systemboard.
October 24th, 2008 at 11:19 am
I believe I am having a similar problem. My laptop dropped off the end of my bed and landed upside down from a fall of above two feet. The thing happened to be in sleep mode when it dropped and upon opening it, the resolution was set lower than it should be, even though vista was telling me the resolution hadn’t been changed, and wouldn’t let me set it any higher.
Point is, after I restarted my computer, the screen will not turn on. I plugged it into my TV via a s video cable and it worked just fine there, but the laptop display simply will not turn on.
It sounds like the display shut off may be stuck off… any help?
October 28th, 2008 at 1:30 pm
When I turn on my laptop the screen does not turn on and it restarts about every 30 seconds, I also tried to display using a monitor but that didnt work either… Could the problem be in the Graphic card?
November 13th, 2008 at 12:54 pm
Many thanks for the instructions on changing the screen. I have an HP Pavilion ZD8228EA and, apart from the fact that there are 5 screws each side, rather than 3, to secure the screen hinges to the cover, the procedure was identical. I found that using a magnetic screwdriver was very useful in locating the screws accurately. Thank you for taking the time to take photographs etc to help novices like me – it really is sincerely appreciated.
November 13th, 2008 at 1:05 pm
Johnny,
Could be bad RAM module. If you have two RAM modules installed, try removing them one by one. Test your laptop with each RAM module separately installed into each slot.
November 17th, 2008 at 1:50 pm
the magnetic switch is located at the left hinge. I am not currently looking at the switch but I am using the dv9000 to type this e-mail and recall it being rather small less than 1/2 in square or round and if I remember correctly it has wires attached that plug in to the main board maybe 2″ or 3″ in length.
November 19th, 2008 at 11:28 am
hi
do you know how to get the 2 covers off the hinges once lcd bezel etc unscrewed and removed? thanks
November 19th, 2008 at 11:32 am
Max,
You’ll have to remove the keyboard bezel first as I explained in the previous disassembly guide for a Pavilion dv9000.
After the keyboard bezel is removed, you can unscrew the hinge cover.
November 25th, 2008 at 2:39 pm
I have a DV9000 that has a black screen, no POST display and then reboots about every 30 seconds too… I’ve pulled the wireless, both HDD, both batteries and both RAM modules just to be sure and then tried just one RAM module each and it does the same thing no matter what the configuration from nothing but the battery to just one each of the HDD and RAM to everything… I even tried booting from a MEMtest86+ and still no display or change… Any other ideas??
November 25th, 2008 at 2:55 pm
Scratch that… Here’s THE ANSWER.
November 25th, 2008 at 2:58 pm
Lloyd,
Thanks for the link.

I have a DV9334US laptop. The screen is blank when you boot up, but if an external monitor is attached, you can see the dos boot screen on it, once windows (Vista) loads as long as nothing attempts to switch video modes, the laptop works perfectly.
But, if you run anything which attampts to switch screen resolutions the screen will go black for approx 30 sec then you get an error regarding the video has stopped responding. Then it works as long as you don’t attempt to switch video modes again.
Does this indicate a bad display or a bad motherboard to you?
December 12th, 2008 at 4:36 pm
I also have the DV9334US laptop and have the same problem was Bill. HP is of no help and the extend service warranty mentioned aboved does not apply to this laptop.
This only started happening after a cross country plane ride (my laptop was in a roller bag) so I’m wondering if something got shook lose?
December 27th, 2008 at 8:21 am
Thanks for the site. I just replaced my Lt hinge on HP dv9000, took about 1 1/2 hours. Instructions were great.
January 3rd, 2009 at 2:53 pm
My HP Pavillion DV9600 screen has a discoloration running up both sides getting wider at the top of each side. HP has said it was caused by me and that I had bruised the screen while cleaning. A bold faced LIE.
They are refusing to honer their warranty.
January 4th, 2009 at 11:53 am
Hi I have a HP Pavilion dv9000 and my screen was blinking like it had a bad connection, I found this site and figured I could dissassemble it,disconnect and reconnect the video line, but I didn’t loosen the bottom screws after you take the plastic framing off, and I bent the LCD..its now cracked and I want to know where to buy a new lcd and if I need a new inverter as well…thanks
January 5th, 2009 at 12:49 am
Bill,
Are you sure the laptop screen is completely blank? Maybe there is a very faint image? Can you look closely at different angles?
Can you see if the LCD screen changes color a little bit when you turn on the laptop? Can you see the backlight at all or the screen is completely black and blank?
If you see a faint image, most likely your problem is related to the inverter board.
I guess your external screen cannot handle different resolution and because of that goes black. It’s normal.
January 5th, 2009 at 12:55 am
John,
Find the HP part number on the back of the LCD screen and google it. Same with the inverter. The part number will look something like that: 432952-001. Could be a different one but same format.
Alternatively, you can search for both parts here. Make sure the part you are buying is compatible with your laptop.
January 11th, 2009 at 1:02 pm
There are a few posts here that sound very similar to my problem. When I power on my dv9500, I get no display on the LCD panel, however, I get video when I connect an external monitor using the VGA port. That got me to thinking, so I went in and changed power settings to do nothing when my display is closed. Now I intermittently get a display, I usually have to restart a couple times, but eventually it comes on. I am fighting with HP right now to cover what I believe to be a faulty display switch module, because it is not covered under the extended warranty enhancement they put out for a lot of dv9000 series laptops, but strangely enough, not for my model. Seeing as this may be a loosing battle for me, I pulled the maintenance manual from HP’s website, and was able to locate the suspected bad module, and will eventually replace it. As stated earlier it is located by the left LCD hinge, and is rather small. If you are experiencing the same display problem I am, and are tech savy, this is a very cheap ($60) fix compared to what HP charges ($300) just for sending a laptop in to be looked at.
January 11th, 2009 at 9:03 pm
Stanley et al…My display quit working a couple of days ago, but flicks on and off as I move the lid up and down. Works fine with external monitor, and flickers on boot up.
Can you tell me how to change what it does when the lid is closed? Thanks. HP wants $450 for me to send it in cuz they say its the screen (not!). It’s a connection somewhere otherwise more would be wrong and it wouldn’t change with lid position, right?
January 22nd, 2009 at 6:15 am
Tanya, you can change the setting for controlling what you laptop does when the lid is closed by going into power options, and look for the link on the left side of the panel.
Actually, as a follow up to my previous post, my problem was not with my display switch. After extensive troubleshooting, I found that my laptop was actually sensing the LCD panel movement, which made me begin to suspect the LCD panel itself. I didn’t have any issues with the image on the screen when it worked, so my focus changed to the display cable. My cable was severely crimped where it passes under the display bezel, and anyone who works with electronics can tell you that a crimped cable can cause a lot of trouble. Replacing the cable fixed my problem.
Tanya, after reading your post, I suggest that you take a look at your display cable, because it sounds to me like you just have a loose connection. If it is secure, the cable itself is about $50 bought through HP, and is an easy fix.
January 25th, 2009 at 5:17 am
How do I get HP to do a “Free out-of-warranty” repair of a Pavillion DV9000 laptop ? I spent over 2 hours on the phone with tech support for which I had to pay $49, only for them to tell me that they would be glad to fix it, for an additional $299 + s/h…. I have had this machine for about 13 months and it is worthless as it sits, I find it hard to swallow that I need to spend what will end up being almost $400 to fix a $750 machine that is just over a year old ….
January 30th, 2009 at 9:48 am
Hi, I’m debating taking apart my dv2000t, the 14.1 inch model, and i was wondering if i could find a source for the problem that i have. My screen blurs out completely for most parts…however, if i start playing with the actual monitor, such as gripping each side and somewhat “tilting” the screen, all of a sudden, perfect picture comes up on my laptop. Of course, as soon as i let go, the screen goes back to being blurred all together. Is this a sensitivity issue, such as some ribbon not being secure anymore, and causing this problem..? Or is it a MUCH bigger one…?
Thanks a lot guys
January 30th, 2009 at 10:13 am
The screen of my dv9000 no longer works and I cannot afford to get a new one, so I’ve just been using an external monitor. Is it possible to entirely remove the laptop screen and just use it as a very thin desktop with the external monitor?
Thanks
January 30th, 2009 at 10:36 am
Asif,
That description sounds like a problem with the LCD screen. I think you have the same problem as it mentioned in the example 7 in this post.
January 30th, 2009 at 10:51 am
Ben,
Yes,it’s possible. You can remove the entire display panel and use the laptop as a very thin desktop, BUT the wireless antenna cables are running inside the display panel and if you remove the display, you’ll loose wireless capability. On the other hand, if you use it only on your desk, you can connect to the Internet via a network cable.
In order to remove the display panel you’ll have to remove the keyboard as I mentioned in my previous disassembly guide for dv9000 series, unplug the video cable, unplug the wireless antenna cables and unscrew display hinges. After that assemble everything back together but without the display panel.
January 31st, 2009 at 10:38 am
Thanks Laptop Tech,
So you’re saying that my only solution is pretty much to replace the LCD screen…? If that is the case, i have a quick question….how much does HP vary when it comes to different models (such as one being Intel, other being AMD) but with SAME sized screens…? The reason I ask is, I have the DV2000T, and I have found a replacement screen, that is ALSO 14.1 inches, for a fairly good price…this is the link
For this 14.1 model, the number is DV2313CL…I have found also another one in the DV2000 series, with model numbe DV2035EA.
So in summary…even though these LCD screens aren’t labeled for sale for DV2000T, since they are in the same product line, and same screen size, can these replacement LCDs work with my computer…?
Thanks a lot once again, I appreciate the help thus far.
February 1st, 2009 at 11:42 am
Asif,
That’s what I think but I could be wrong.
Based on my experience, it feels like a defective LCD screen.
I don’t know. Different screens might require different wiring (different LCD cables).
Maybe you should search for a new replacement screen using the HP part number from the old screen? That’s would be the best way to go. Just to make sure that you buy a compatible screen.
I just searched through the maintenance and service guide for HP Pavilion dv2313cl notebook and I found that HP lists four different LCDs for that model. It’s not very clear which one you should use. Here’s the list of LCDs I found in the guide:
Display panels:
For use with full-featured computer models 430457-001
For use with defeatured computer models 430458-001
For use with dv2200 models, BV panel 435842-001
For use with dv2200 models, AG panel 435843-001
I guess you’ll have to remove the LCD, find the HP part number from the LCD, and search by that part number.
February 7th, 2009 at 4:34 am
Hi all,
I was wondering if you can help me diagnose this.
My DV9008tx is 2 years old and when turned on has only white vertical lines/panels of different shades about an inch wide across the screen.
When hooked to external lcd, t will only boot in safe mode low res and has dotted vertical lines down the panel.
Do you think this is a Motherboard or inverter? I wish to fix it myself and the MB is quite expensive….
Cheers for any advice! Dale.
February 7th, 2009 at 10:18 am
Dale,
Even though the laptop screen displays only white vertical lines, you still can see them and the LCD is bright, correct? That means the backlight and inverter work properly. It’s not an inverter related problem.
In your case both screens, internal and external, display a garbled image. Most likely you have a problem with the video card.
I’m not sure 100% but I think the video card in this laptop is integrated into the motherboard and cannot be removed or replaced separately. That means you’ll have to replace the whole motherboard.
Did you find a link about free HP repairs for dv9000 laptops? Did you try calling them and find out if your laptop qualifies for a free repair? Try that option first.
February 7th, 2009 at 7:47 pm
Did you find a link about free HP repairs for dv9000 laptops? Did you try calling them and find out if your laptop qualifies for a free repair? Try that option first.
I am in Australia and my model doesn’t qualify…
Thanks for the fast reply anyway… I will try to get the MB from China as it costs US$550 AUD$800 unfitted here…
Cheers, Dale.
February 8th, 2009 at 3:49 pm
My dv9500 has just passed 2 months after the warranty expiration. When booting up I have 4 screens shrunken for the display. I can only boot in safe mode, which I still end up with 4 shrunken screens. I think the booting up issue came after the shrunken screens started occuring. I am thinking kids and wife rebooted several times trying to get rid of the wied display. Any ideas?
February 9th, 2009 at 12:37 am
Byron,
Did you test your laptop with an external monitor attached to the VGA port? Can you see if the external video works properly or it has same 4 shrunken screens?
Also, when you start the laptop there should be HP logo. Does it appear in four screens too or this problem appears only in Windows?
February 11th, 2009 at 12:09 pm
Thanks a lot for the help, I’ll try it out… is there any way of removing it and still keeping the wireless antenna connected?
February 18th, 2009 at 2:59 pm
alright well i took the screen off, unscrewed the wireless antenna’s from the back of the screen and left them connected to the wi-fi card and my wireless still works! thanks for the help
March 4th, 2009 at 1:02 am
Thanks so much in your INFO about removing the screen as i only wanted to remove the inverter as mine was dark on one side of the screen. I got the part number and order the new part and having installed the old inverter my screen is tops again. The new part is costing $23 AUD and a shop wanted $300 AUD to do the same job. I cant thank you enough.
March 13th, 2009 at 6:01 pm
hi, I have HP Pavillion series, I had problem with my laptop a month ago, the screen was totally black an blank but its still charging and when i turn it on the lights are on. when i brought it for repair the technician said it was the mother board that was brocken, can it be? how much will it cost me for that board? Please help me…
March 15th, 2009 at 4:28 pm
michelle,
I cannot tell you what is wrong without testing the laptop. Yes, it’s possible that you have a bad motherboard.
Could be connection relate problem, bad memory, bad video cable, bad motherboard, etc…
It depends on the model of your laptop. Could be $100 or could be $500. You didn’t give me enough information.
March 21st, 2009 at 4:38 pm
Thanks for all the info. I just had my DV9408 motherboard replaced under the extended warranty as it would not start (blue lights would just flash and keep trying to restart). When I got it back, it started up but the screen is dark (like looking through a deep tint). External monitor works fine and when lid is closed, the system goes into standby ok so lid switch is ok (for those looking, the lid switch is located under the speaker cover near the start button and is glued to the heatsink). I am going to try to get HP to cover the screen under the extended warranty but they have said intially that they won’t as there had been a spill (which is true but was minor about 1 year ago and everything had been working fine, including the screen). If they do not cover this, am I safe to presume that it would be the inverter? The HP rep thought it would be the backlight but they really did not seem to know. Again, great site. Thanks for the info.
March 23rd, 2009 at 9:00 pm
Peter,
It’s hard to tell. Could be bad backlight lamp or could be bad inverter. The only way to find out is install a known good inverter and test the laptop.
I would try replacing the inverter board first. It’s easy to replace and shouldn’t be very expensive.
March 28th, 2009 at 8:29 am
My HP Pavillion 9000 is 17 months old. The left rear lower corner of the cover (as you face it) has cracked, the hinge has virtually frozen up and now the screen cover has cracked. Is this a common occurance on these? I’m handicapped and never take my laptop out of my room and always close it from the center…Thanks
March 31st, 2009 at 4:40 am
Hello,
I removed my cracked LCD screen and took out the inverter. There is a set of black and white wires that ran out of the inverter. I broke the white glass tube. Where can I find a replacement and do you have any photos or instructions on where those wires are supposed to go? Thanks!
March 31st, 2009 at 8:23 am
there actualy is a magnet, its located on the left side of screen about 10% from the botton of the screen.
April 1st, 2009 at 4:41 pm
Hello,
Would you please give me input on what I should do regarding my previous question (#44) as I’m concerned that it will happen again when repaired. I paid over $900.00 only to have to spend more money 17 mos. later. Thanks
April 1st, 2009 at 10:23 pm
Mike,
Looks like it’s a common problem with HP Pavilion dv9000 laptops.
If you Google for HP dv9000 hinge crack, you’ll see that many other people have the same issue with their dv9000 laptops.
April 4th, 2009 at 8:48 pm
I have a dv6308nr and the wire that connects the inverter to the motherboard got burnt. It made for some reason contact with the body of the lcd screen. Now I´ve tried a different inverter with a different wire but the laptop stays off. It can´t be turned on. But as soon as I attached an external screen through the vga port it turns on and everything works. My question is: is something not working on the motherboard? Some advice would be very helpful.
April 5th, 2009 at 10:05 am
thank you so much for this excellent and easy tutorial; was able to fix a friends laptop in under 60 minutes.
April 5th, 2009 at 12:04 pm
Robby,
Sounds like a problem with the motherboard, apparently you shorted something.
April 8th, 2009 at 7:51 pm
Hey, I have an HP Pavillion dv9000, for a little over a year, and about 5 months after I got it I started having a problem with the LCD. It shows pink and green lines down the screen, and depending on how I tilt the screen, I can see. Well it worked fine for a while, but now i need to tilt it SO MUCH that i can’t even see it properly because of the angle. Help! Everything else is awesome.
April 12th, 2009 at 7:59 pm
Indy,
Why did you wait for so long and didn’t take it to the authorized repair center? I guess it’s not under warranty anymore?
OK, what about these lines? Do they appear on the entire screen or in random places?
April 15th, 2009 at 10:48 am
Hi
thanks for a really helpful guide. I think I will be able to adapt it to changing the screen on my HP 510 notebook. One question though – I dropped my laptop and the screen has a number of cracks. It’s still working but I have a number of black lines running along the cracks. Would replacing the screen be the right thing to do?
thanks
April 16th, 2009 at 3:52 pm
First of all, excellent job on giving these free classes to fix laptops. My DV9330 shows a blank screen and scrambled colors on the video output, it just got a scramble colors screen one day and the next day showed a driver problem, hit safe mode, and no screen output since then. No faint image. I hear HDD working, DVD works, I have tried memories swaping, but still nothing. Out of warranty and not covered by HP. I am not sure if LCD is faulty, but I am thinking on the motherboard. Can you tell me what are the diagnostics for a faulty motherboard? Thanks in advance.
April 19th, 2009 at 11:04 pm
cliff,
That’s the only option you have. Or you can use the laptop as is (with a cracked screen) but output image on the external monitor.
April 19th, 2009 at 11:43 pm
Neil,
For some reason, your description sounds like a problem with the video card which is integrated into the motherboard, so basically it’s a motherboard problem.
When you have a faulty LCD screen, the laptop still should work with an external monitor attached to the VGA port. Test your laptop with an external monitor? Can you make it work this way? If not, most likely it’s bad motherboard.
April 20th, 2009 at 5:01 pm
Thanks for your prompt answer. I have tried with an external monitor but the output is a scrambled screen of small squares. Can you suggest me a web page to order the motherboard? Is replacing this motherboard too difficult to do it myself?
April 21st, 2009 at 11:47 am
Neil,
Apparently it’s related to the video card and means the whole motherboard has to be replaced.
I don’t know any I can suggest. Find the motherboard part number (SPS number in the memory stick) and google it. You can find a seller this way.
April 21st, 2009 at 5:12 pm
Hi, i have a DV9653CL accidentally i drop my laptopp and the LCD crack, i buy a new one and replace it but now when i turn it on it turn on and the turns off i change the inverter trying to figure it out bu i still have the same problem! what do you think it could be?
April 21st, 2009 at 5:16 pm
Hey when i remove the Cable that goes to the LCD and the Inverter the laptop contious on! it doesn’t goes OFF. what this sign could be?
April 22nd, 2009 at 11:33 am
MasterM,
What if you install the cracked LCD screen back into the laptop, will it stay on?
If the laptop stays on with the old cracked screen but shuts off when the new screen is installed, apparently the new screen is not compatible with you laptop and maybe requires a different video cable or the new screen is defective.
Before you jump to any conclusion, test the laptop with the old screen.
April 24th, 2009 at 6:30 am
Hi Laptop Tech,
The new LCD Screen its brand new! but the Laptop shuts off with the old one and the new one.! when i remove the cable from the motherboard the laptop contiuons ON and i can connect and external monitor and it works perfectlly.! what do you think it could be?
May 10th, 2009 at 3:02 pm
Thanks for the useful post. Unfortunately, when I followed the instructions using my HP Pavilion DV9000, the inverter looks nothing like the one you have pictured above. Mine is twice as wide and has two plugs on the right hand side. The part I ordered from your link obviously is not compatible, so I have a useless part now. Where can I get the correct part?
May 11th, 2009 at 11:55 am
I mistenly left this on the wrong blog previously. My bad. I followed your instructions about replacing the inverter on my hp dv9000 but I still get a screen that can only be displayed by using a flashlight. Any other suggestions?
May 12th, 2009 at 6:14 am
Can I remove the rest of the screen case. The laptop still works with an external minitor but now the screen is just in the way.
Thanks!
Ben
May 21st, 2009 at 6:03 am
Is there anything about replacing the fan in a HP Pavillion dv9000.
Thanks Jim
May 25th, 2009 at 4:44 pm
Jim,
You can find these instructions in this service manual for HP Pavilion dv9000 notebook. You’ll find the cooling fan removal instructions in the chapter 5.25
June 7th, 2009 at 11:00 am
I have a dv9000 (exact model dv9927cl). Im using it right now to write this using an external monitor as the lcd doesnt work at all. The computer physically is fine only the lcd doesnt work at all. In fact the computer doesnt even see that an lcd exists. I followed your great instructions, thank btw, and checked both ends of the lcd cable, which were fine amd the cable looks fine. any more trouble shooting i can do to find the problem. I will add on thursday I turned it on and had its lcd working and a secondary display thru svideo, i left and returned to find the lcd black. couple power off and on and the lcd returned. next day turned onand found black lcd and has never returned since. ant\y thoughts?
June 11th, 2009 at 5:42 am
What is that yellow tape surrounding the video cable (right by the sticky tape)? I inadvertantly thought that was the sticky tape and removed it as well. Doesn’t look like it will be an issue but I want to confirm that before I put the new screen in.

I have to replace the lCD screen of dv6000 series. I am looking for the cheapest possible solution. what specifications should I look for a screen? Please suggest
June 18th, 2009 at 7:53 pm
question for ya
My laptop screen is showing a split screen, a top and a bottom with both showing the same image. The screen is somewhat readable but kind of garbled. I can only boot into safe mode, I did full system restore and nothing has changed. Do you think its the motherboard or screen? My warranty is over and I dont qualify for the out of warranty fix
. any help?
June 23rd, 2009 at 3:01 pm
my hp dv9000 slid off my couch and now if I open it more than 45 degrees what is black on the screen becomes red. After being open only that much for a short time it can be opened slightly further. I was hoping something was loose and by unplugging and replugging it would be fixed. What should I do? My warrenty ran out and I didn’t get the extended warrenty
June 23rd, 2009 at 9:54 pm
Looks like Indy Indy B had mentioned “It shows pink and green lines down the screen, and depending on how I tilt the screen, I can see. Well it worked fine for a while, but now i need to tilt it SO MUCH that i can’t even see it properly because of the angle.” – a do not share his “awesome” view on other HP Pavilion features, nevertheless have experienced just the same issue on my HP.
My question is, before I damage or break anything
, is it any worth in your opinion to open the screen lid?
Imean do you think that the lines may be a poor connection tape contact /worn out tape, or some other easy-to-fix issue? There is one, sometimes 3 1-pixel thick vertical colour lines across the screen, varies on the screen angle, they would sometimes disappear when you “bend” or “tilt” the screen gently each side in opposite direction.

Adam,
First of all, test your laptop with an external monitor. If external video has same lines, your problem is related to the video card and opening the screen will not help at all.
I’m pretty sure this is a problem with the LCD screen, not the cable or connection. When you get a few vertical 1-pixel lines, it’s bad LCD.
You’ll have to replace the LCD screen.
June 24th, 2009 at 10:36 am
AMANDA,
It’s possible that the video cable got loose and is not making good contact with the motherboard. I would check connection between the video cable and motherboard and make sure the cable is connected properly.
June 24th, 2009 at 12:36 pm
jamey,
Test your laptop with an external monitor. If video on the external monitor looks normal, I think you have a problem with the LCD screen in your laptop.
June 24th, 2009 at 12:42 pm
Chandy,
Type of the screen and resolution. XGA, WXGA, SXGA, etc… Look at the chart on the bottom here.
June 26th, 2009 at 10:46 pm
hi there
this site is very informative. coulkd you take a look at this picture and tell me how i can fix this problem? whether its my lcd or what?
cheers. i’ve got white patches running down the screen. when i plug external monitor in it works fine.
cheers.

I tried with an external montior. After a full system restore it work for about 2 minutes and then I get the same split screen deal. I’m at a lost.
I was thinking of just getting a new motherboard.
July 1st, 2009 at 9:34 am
jamey,
If I understand correctly, you are getting exactly the same problem on both screens, the internal LCD and external monitor.
If the internal and external video fails the same way, your problem must be related to the video card. In most laptops the video card is integrated into the motherboard, so it makes it bad motherboard. That’s my guess.
July 5th, 2009 at 1:05 pm
My problem is very similar to AMANDA’s (post and reply below) except mine didn’t take a header and it’s not the black that get’s red. Instead it’s the white or very light portions.

Could you point me to where I can find help on checking the connection between the video cable and motherboard and make sure the cable is connected properly.
Thanks a million for such a helpful site!!!
July 6th, 2009 at 10:28 pm
Lisa,
Basically, you’ll have to disassemble the laptop to the point where you can access the video cable. The video cable connector can be found under the keyboard cover. I explain how to remove the keyboard cover in this guide.
I don’t know if reconnecting the problem will fix your problem, it was just a suggestions I would try first as a technician.

I have the HP Pavilion DV9000, and my laptop hit the table pretty hard. Not my screen is gray in color – it has light, but no color or picture. I did plug into a monitor and it showed fine on that screen. I opened the screen and it all looks like it is connected fine. Any other ideas?
July 7th, 2009 at 6:13 pm
I have HP dv9000 laptop and my screen flickers and then turns off. I can definitely see something is displayed on the screen if I look closely, it just seems that the backlight is not working. If I close the lib and open it again it flickers on and sometimes stays on, but lately if I close and open the lib it just briefly flickers and stays off.
Do you think it’s just a loose connection or do I need to replace the inverter or even replace the entire LCD screen?
Thanks, Frank
July 8th, 2009 at 3:32 am
I had the same problem with the post above me and it was an inverter problem
Right now I’m having an issue with different parts of my screen flickering low, I think its a backlight problem but I don’t know really. Since I replaced the inverter recently i dont think its that but I’m not sure, if it is the backlight I need to find a way to replace the backlight on the screen.
July 8th, 2009 at 5:45 am
Okay so heres the deal. I dropped a glass of water on my laptop (i was trying to hold it in my mouth while carrying my laptop). I figured out that wasnt such a good idea. XD. I quickly turned it off and cracked it open hoping it would dry out. I started it up a couple days later and it works. Only thing wrong is my keyboard is freaking out (i have a new one coming). Also the screen is VERY dim. I need a flashlight to see anything. Later i took the casing off the lcd and found the inverter was very wet. So i ordered that also. If that doesnt solve my problems is there any way to get new back lights without buying a brand new lcd? that would suck Thx!

My Issue is that I accidently sat on my Laptop. My screen now looks like someone through a baseball at it. There is a while section that goes down the middle at the top it looks like cracked glass. The laptop is not cracked but that is what it looks like. What should I do? Thanks Everyone.

Guys my HP Pavilion dv9000 wont start when i press the power button, i put the charger but still wont work, the power led wont light, only the charger led is on…..pls help me guys how to troubleshoot this… tia.

ill turm the power botton on and it take a few trys and then the lighs stay on but the screen dosent come up at all and then the lighs restart and then turn off after a wile what could be the proble here ay one heard of this problem?
July 19th, 2009 at 12:19 am
ed,
First of all, test the AC adapter. Maybe the adapter is bad and the battery is completely discharged.
If the adapter is working correctly, there could be a problem with the motherboard. Can you test the adapter?
July 19th, 2009 at 12:21 am
yob,
1. Unplug the charger.
2. Remove the battery.
3. Wait for a few minutes.
4. Plug in the charger and try turning it on.

please help, here is a story.
I have Pavilion dv9308nr laptop, couple of weeks ago my left hinge broke and Hp wont fix it cause I’m out of warranty. When my hinge broke I was still doing some work on that laptop, then all of a sudden the screen went black, everything gone and I tried to turn it back on, but it turns off and on every 15 sec automatically and nothing on the screen.
I found your website and followed the article on how to replace hinges and back lid, i did ok everything looks like brand new, but still no screen and laptops keeps turning off and on every 15 sec. I did a lot of testing that you were telling us, such as removed a battery in order to get rid of static alec. Still nothing. What i also discovered is that if you keep pressing F10 key when you turning on notebook it will stop turning of by itself, but still no screen.
I ordered one inverter just in case and i’m still waiting for shipping. I will try to replace it and maybe everything going to be alright. Cause if it turns out that my motherboard is dead then this notebook is no longer useful. To much money for replacement motherboard it doesn’t worth it, better to add couple bucks and buy new one.
Questing is… Do you guys have any ideas why notebook keeps turning off and on? Maybe when the hinges were broken and i pulled the video cable which is under left hinge and cut it inside somehow? I just can’t get it. So when it starts to boot bios doesn’t see the screen and shuts it of maybe. Any Idea.
July 25th, 2009 at 3:54 pm
I have the “flickering pink” screen problem. When I open up my laptop, the screen turns a fuzzy pink. I have to find the perfect screen angle so that it stays white. Anything I can do at home to remedy this?
July 31st, 2009 at 7:19 am
Hi I have the same problem as Frank #85. I’m not sure what is the problem, but the screen is on and starts flickering and finally dies. However, upon closing the lid and opening, sometimes it brings the screen back on, but the flicker comes back and the screen dies again. There’s something you can see under light that the background is still there, but with no light.
HP is going to charge a bomb for this, and I tried the connectors which are well connected.
Any ideas?
Thanks
August 1st, 2009 at 7:36 pm
Hi, I have the exact same problem as Cameron above — the flickering pink screen. What do I do??? Thank you!
August 3rd, 2009 at 6:14 am
Hi i was wondering if doing this and then reassembling the screen would fix these vertical pixel lines i get down the left side of my screen

Hi
My original question was – when I disconnect the main power lead from HP Pavilion zd7143ea 17 inch laptop screen goes dead but PC still functions. Any suggestions?
Thanks
Billybean
August 13th, 2009 at 1:50 pm
Billybean,
Not a common failure. Not sure what’s going on.
What if you turn off the laptop, unplug the power adapter and start the laptop from the battery. Does the screen turn on this way?
Check for the BIOS update. If there is a newer version available, try updating the BIOS.
August 14th, 2009 at 10:55 am
Hi Laptop Tech,
I have a HP DV9000 series laptop and have been experiencing LCD issues (fuzzy display when LCD opened to a certain position). Without going into the boring details, I removed the screen bezel to see if the issue was a loose connector. What I found was a short in the cable/wire (left side of the inverter) which goes through the hinge. Do you think the short is something that I can remedy myself?
Thanks in advance and thanks for hosting an awesome site to help us non-techies!
P.S. will you be using PayPal anytime soon for your donations?
August 16th, 2009 at 9:53 am
Hi Laptop Tech,
Thanks for all the info! My dv9000 was dropped breaking the hinge. Replaced it to solve problem but then left hinge broke (I guess weaker than the new one). Replaced it and have another broken on right!. Will replace both together but main problem is sometimes the computer wont start. I get all sorts of flickering colors, lines, blocks, waves, etc. I get a message to perform start up repair and that usually works but sometimes takes a time or two. I think I may have a short or open in the cable going through one or both of the hinges. Does that make sense? I do have a second identical laptop that I can swap parts with. Any suggestions?
August 17th, 2009 at 12:03 pm
I have an HP Pavillion dv9000, for a little over a year, and about 1 yearafter I got it I started having a problem with the LCD. It shows pink and green lines , and depending on how I tilt the screen, I can see.
whole screen is pink lines…..
u got soultion
i give it to hp repire centre
August 18th, 2009 at 11:09 am
jen,
That could be bad screen, faulty video cable, poor connection between the video cable and screen.
If the same problem appears on the external monitor, you have a problem with the video card.
August 22nd, 2009 at 1:50 pm
Hello there Laptop Tech,
First of all I want to thank you for your awesome job with describing the steps needed to take the lid apart. Here is my problem, sorry for the length but rather give you as much detail as possible:
I have a HP DV9009US here that is out of the free limited warranty repair that has a very faint image on the screen. A few days ago Windows would boot up fine using an external monitor but now right before the splash screen is done loading the monitor goes to sleep. Windows continues to load and you can hear the Windows welcome music from the speakers. The laptop will boot up fine in safe mode using an external monitor and also in VGA mode, but when you change the display settings in VGA mode the monitor then fades to black. Last known good config also does the same thing as booting up normally. I purchased a compatible power inverter and installed it but there still is no image on the screen. I then purchased a new compatible backlight and installed it. I plugged in the LCD cable to the screen but before I put all the screws back in place and even fit the backlight into the screen I wanted to test it to make sure it worked, however, there is no light coming from it. I tried swapping both the old inverter and new one in combination with the new and old backlight but no dice. One thing that I have noticed is that there is a strange oder, which I can’t put my finger on what it smells like, is coming from the laptop at boot up but starts to diminish the longer the laptop stays on. I really don’t know what else to try at this point. Would clearing the CMOS work in this instance? And this couldn’t be a result of a virus, could it? Any help will be grateful.
Thanks tons in advance!

Hi
I have a compaq C751NR. When i open up the laptop the screen has a blueish red distortion to it. I checked it against another lcd screen and didnt see the same problem. I also took it apart and check the lcd cable. I am not sure what it could be. I almost think it might be inverter. I am not sure what will happen to the display if it is bad.
August 24th, 2009 at 10:18 pm
Laptop Tech,
I´m having a problem with my left screen hinge. On November(2008) HP launched on their website a 6 month “Limited Service Enhancement” to fix this problem, however by the time I noticed this costless repair given by HP, it had expired the date limit. Since I´m from Brazil and these kind of services given by the local HP retailers are expensive, I would like to know how to try and fix this problem by myself. Thanks and hope to hear from you soon.

Hey there, great how too on the screen removal. I dropped my laptop off the bed last night while working and this morning when I booted up I have a pinky/green screen. Is this the Inverter or do you think it is something more serious?
It is for businss so I am in deep if I can’t get this fixed.
Apprecaite your help.
Phil
HP Pavillion DV9000
August 26th, 2009 at 8:14 pm
Phil,
If you can see the screen and it’s bright, it means the backlight/inverter work fine. So it’s not related to the inverter board.
I think it’s either loose connection between the video cable and motherboard/LCD (less likely) or you’ve damaged the LCD screen (more likely).
You can try reseating the video cable just in case. If it doesn’t help, most likely you’ll have to replace the screen.
August 30th, 2009 at 6:37 am
Hi
Tried your suggestions. No change. Wont be available ’til October for further suggestions.
Thanks

hi i have a hp dv 9000 series laptop, the screen becomes distorted when you move the lcd lid and also there is no sound coming from the speakers, right now the screen works great if i dont move the lid, but sound never works unless i use the audio out jack
September 1st, 2009 at 11:19 am
Thank you! I will be donating to you as soon as I get it fixed. My left hinge broke. Hp will only fix it for $150. I told them I will fix it myself [thanks to you!].
I don’t know if mine is a single or dual lamp. Does it matter? guess i will get the part number off of mine.
Thanks again!!
September 2nd, 2009 at 4:03 am
I have a pavilion dv9605ea with a screen problem. My laptops out of warranty and after phoning Hp they want to charge me £280+ to even have a look at it and £15 to actually speak to someone for advice. Im not to sure if this is even a major problem or something I could fix myself. My screen kept freezing with lines and colours and for a while if you moved the screen slightly or supported the screen a little by putting your hand under the left hand side near the join this would fix it but now no matter what you do the screen is just fuzz.I have connected laptop upto external screen and it works fine but kinda makes it useless as a portable laptop. Iv edisconnected and re-attached the video cable and its still the same. By the way is the video cable meant to go under the left hand hinge all crumpled looking? Thanks in advance for any help youre my last chance before throwing this out of the window
September 7th, 2009 at 12:53 pm
HP DV9000 (Model: HP DV9750ea).
If I open lid all the way and switch on, the screen remains blank but windows boots (i can hear the sound).
If I open lid only 1/2 an inch and switch on, the screen is fine. I wait for windows to FULLY LOAD and then open the lid all the way and everything works perfectly.
I want to find out what is causing this as it must be fixable.
Any ideas?
Great article.
September 8th, 2009 at 7:58 pm
billmad,
This is not a common failure and it’s hard to tell what is causing the problem.
I think it’s related to the video cable somehow. Maybe the video cable is not making good connection with the LCD screen or motherboard. Try reconnecting the cable.
Also, it’s possible there is a short inside the cable and it has to be replaced.
September 9th, 2009 at 11:08 am
… If I open lid all the way and switch on, the screen remains blank but windows boots (i can hear the sound) …
i have a similar problem since today. my screen just stopped responding. it boot’s on an external screen only if i select VGA it the boot options. Then xp loads. if i don’t choose that vga option, i get the xp splash screen but then my external screen turn off and the boot does not finish. I know it doesn’t because of the sound i’m not getting.
I followed your explenation to open up and check if its a wire problem, fiddled with no success. Should someone find the fix to the problem, i would like to know.
September 10th, 2009 at 9:20 pm
paul,
Do you get anything on the laptop screen at all? Does it change color a little bit on startup? Can you see a very faint image if you look very closely?
September 15th, 2009 at 8:18 pm
I have a dv9000, the screen comes on great then goes black after a few seconds, if i close the lid and re-open its fine again for a while then goes black again, if i open and close lid ok again, etc etc. Could this be inverter or cable or more likely the screen thats faulty.
Thanks
September 16th, 2009 at 6:44 pm
I think my webcam is defective. Would I have to remove the LCD screen to replace it? Or is there something else i would have to do? It’s not being detected by the laptop.
September 17th, 2009 at 12:24 am
I have a HP DV6000 laptop, the screen is faulty.
I would like to try and determine if its the LCD or the inverter or the motherboard.
If i link to external monitor the external image is fine.
The laptop screen flickers and shows the image for a fraction of a second then continuously comes and goes. Any guidance much appreciated.
September 19th, 2009 at 12:19 pm
BBOR,
It’s not very clear from your description if you are experiencing a problem with the backlight or image itself. Which one comes and goes, the backlight or the image?
Most likely the motherboard is OK because the laptop works fine with external monitor.
If the backlight flickers but the image is always on the screen, it’s either bad inverter or backlight lamp inside the screen. I cannot tell which one is bad because both have very similar failure symptoms. I would try replacing the inverter board first. There is a very good chance to fix the problem.
If the image flickers but the backligth is always on the screen, it’s possible that you have a problem with the video cable.
September 19th, 2009 at 12:47 pm
Caled,
You don’t have to remove the LCD screen but you’ll have to remove the front bezel. The webcam is mounted above the screen.
Can you see the webcam entry in the device manager? Try removing the webcam from device manager, restart the laptop and let it re-detect the webcam.
September 19th, 2009 at 1:10 pm
Alan,
1. This problem is not related to the video cable.
2. Could be either bad inverter or backligth. You cannot tell without testing the laptop with a known good inverter or backlight lamp.
If you have to guess, try replacing the inverter board first. It’s not expensive and takes only 10-15 minutes. You have a good chance to fix the problem.
September 24th, 2009 at 4:43 pm
I have a dv9700. the LCD has no picture, when plugged into external monitor the picture is fine. Replaced LCD and still no picture. Any ideas?
September 24th, 2009 at 9:57 pm
NICK,
Are you sure that there is no image at all? Take a very close look at the screen. Maybe the image is there but it’s very faint?
Does the backlight work?
September 25th, 2009 at 6:41 am
No image. it never changes when you power up the laptop. I thought it would b the lcd b/c 1) the image is fine on other monitors 2) no image at all on lcd. but i was wrong and i cant figure out what it could be.
September 26th, 2009 at 1:22 pm
NICK,
I guess you already tried switching video from external to internal mode using Fn+F4 shortcut, right?
1. Could be loose connection between the video cable and motherboard (you’ve already reseated connection on the LCD). Remove the keyboard bezel and try reconnecting the cable.
2. Could be bad video cable. Try replacing the cable.
3. Could be a problem with the motherboard. It’s not likely because you still have image on the external monitor, but it’s possible.
September 27th, 2009 at 10:30 am
I have a HP dv9000 and when I open the LCD lid to a usable position my screen is fuzzy. If I move the lid, usually closer to the closed position I can get the picture to come in perfect. The laptop has not been dropped, and I don’t know how to tell if the hinge it broken. Please help. Thanks!
October 1st, 2009 at 6:23 am
I have a HP pavilion zd8000 and the monitor has become full of vertical thin lines of different colours. It started with a few , now it has dozens. I plugged the laptop to an extenal monitor and the image was fine. I assume its the monitor that isn´t working well. Can u helpme please?

MY LAPTOP HAD A BROKEN SCREEN I BUY ONE FROM EBAY BUT WHEN I PLUGIN LIGHTS UP BUT DOESN`T DISPLAY THE os
October 5th, 2009 at 8:54 am
My HP Pavillion dv9000’s screen is grey. The external monitor only works in safe mode and has a big grey splash in the upper left corner. The computer seems to work fine ie: wireless internet, programs, updates ect. The external monitor’s resolution is 640 x 480 and I cannot change it. (it is also and HP). Is my video card bad? Can this be fixed? My warranty is up.
Thank You,
Kim
October 7th, 2009 at 9:22 pm
Kim Hutton,
Sounds like a problem with the video card. It’s integrated into the motherboard, so the whole motherboard has to be replaced.
If your laptop qualifies, you still can get a free repair from HP. Check out this service enhancement program.
October 7th, 2009 at 9:54 pm
ALBERT,
Check connection between the video cable and LCD screen. Maybe it’s not plugged correctly.
Try installing the cracked screen back into the laptop. You were able to see some image on the undamaged part, right? If the old cracked screen shows image, but the new screen doesn’t, the new screen is defective OR not compatible with your laptop.
October 7th, 2009 at 10:07 pm
FASSP,
Yep, sounds like a failing LCD screen. You’ll have to replace the screen.
October 9th, 2009 at 10:42 pm
I have a dv9500 the backlight is out but, I’m not sure how to replace it. Is there a tutorial on this?
October 17th, 2009 at 2:53 pm
Will you please you do a step by step on changing the graphics card in a dv9000 series hp laptop? I want to upgrade it but cannot figure out how to get to it inside the computer.
October 19th, 2009 at 5:19 pm
Very happy about this.
Helped me alot.
Now i have my HP working again.
October 21st, 2009 at 4:43 am
Help – I have a hp Pavilion DV9810us (dv9000) laptop 5 months out of warranty. Screen goes to near black at certain angles (even at bios screen). You can still see that icons/programs are running. If you move the screen back to about 90 degrees (and other angles), then the screen displays properly. HP will not help unless I send in for $400. Updated bios and video drivers(no effect). Any ideas if this may be related to inverter or other screen problem? thanks
October 22nd, 2009 at 7:07 pm
Mike,
I don’t think this is inverter problem because the scree works fine at some angles.
Could be:
1. Bad connection between the video cable and inverter/LCD screen. Try reconnecting the cable.
2. Bac connection between the video cable and motherboard. Try reconnecting the cable.
3. Bad video cable. Try replacing the cable.
October 26th, 2009 at 4:16 am
I have very similar problems as mentioned above. I have a HP DV9000 notebook. All I get on the screen is the backlight is on, however other than that it is black. I can however connect an external monitor via VGA port and get somewhat of a picture. I can only boot into safe mode this way though and when it does boot up the resolution is at 4bit color and only 640×480. If I try to boot normally, it says windows has recovered from an error (page fault in a nonpaged area). It does a memeory dump and boots, however only to revert back to this error. I have been having problems recently with the computer not shutting off when closing the lid every once in a while too. Now when the ext. monitor is connected I can shut the lid and it stays running. Does this sound like a bad lid swith module, inverter or possibly motherboard. I refuse to send it back to HP for $400. Thanks for any help.
October 26th, 2009 at 12:04 pm
hey there,
Boy sounds like Im in the right place! I have a dv9000 series monitor went very dark while using it.. With the lights on n the room I can see shadows of whatever im doing. ( not brightness control checked that first and yes its 31 days out of warranty.
I ordered and recieved an inverter from hp and installed it. made no change at all in the display. Since this happened I have been connected to an external monitor and everything works just fine. (just a paint in the a@#.)
I have ordered a display panel and am going to replace it myself as per your instruction on this site. Anything I should watch out for?
October 27th, 2009 at 11:52 am
Thanks for response to post #140 – Dark/Black screen issue – its not the inverter like you said. I’m focusing on the cable now. I’ll update once i check the connection between motherboard and cable or replace the cable.
October 27th, 2009 at 7:17 pm
First off, what an awesome site!
I was wondering if you may be able to diagnose my problem =)
I have an HP DV1000 laptop, just today I started to have problems with the backlight of my LCD screen. When I start it up from standby, it seems to have issues keeping the backlight on. The backlight will stay on for about 5 seconds then it turns off. I press on the switch that’s triggered when the lid is closed on & off a few times and it’ll turn back on for a few moments then shut off again. After a minute or so of doing this the backlight seems to stay on.
Any help or advice would be greatly appreciated, Thanks!

Ryan,
It’s either bad inverter board or faulty backlight lamp inside the LCD screen.
I would definitely try replacing the inverter board first.
October 27th, 2009 at 8:55 pm
Cindy,
If a know good inverter didn’t fix the problem, it’s very likely that there is a problem with the backlight lamp inside the LCD screen.
It’s really hard to give a good advice to someone who never don it before. Do not hurry. Pay attention to all details.

Erich,
I think you have another dv9000 with the video chip failure. A very common failure for this model and HP even fixing some dv9000 laptop at no charge. Take a look at this post, maybe your laptop qualifies for a free repair.
The problem is not related to the lid close switch or inverter. Most likely you have a faulty video chip, so the whole motherboard has to be replaced.

Ref: Post # 140 – Dark/Black screen issue on dv9000 – Issue was fixed by replacing bad video cable. Thanks very much.
October 31st, 2009 at 9:17 am
Ref Post #145 – Thank you so much for your advice! The new inverter board fixed the problem of the backlight turning off. =)

hi laptop tech
I posted earlier about replacing dispay panel. got panel and exchanged it with mine with no problem. Your instructions are awesome. Turned computer on and same problem…. can see only shadows. only differance now is under device manager I have a yellow exclamaition next to the microsoft ISATAP adapter #8. I clicked on in and requested update drivers online. it said most current is installed :copy and paste message below.
This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)
what does this mean and what do I do. I looke it up online but dont understand what its for?
Help please

Ryan,
You are welcome! That’s why you replace the inverter first. It’s not a difficult repair and there is a good chance to fix the problem.
November 2nd, 2009 at 3:39 pm
cindy,
Did you replace just the LCD screen or the entire display assembly (LCD, inverter, cables, plastic parts…)?
If you replaced just the LCD screen but still no backlight, most likely it’s a bad inverter.
I don’t know what this error means.

I have an HP Pavillion DV9408CA, the screen goes black and occassionally it comes back. Implies lose connection someplace. What would be my best route of action to resolve the off-warranty issue? Rather not plug in to a monitor as this ends the portability. Your assistance is greatly appreciated. My repair experience is limited to desktops but still knowledgable enough. Thank you
November 7th, 2009 at 10:23 am
I have a hp Pavilion DV9605ea (dv9000) laptop about 6 months out of warranty. At certain angles I get green pixelation/fuzziness, but In a more close position the screen displays perfectly. The distorted image appears to effect video files and images most. Otherwise the laptop functions normally.
I have tried with another LCD screen, the second lcd screen displays fine until I boot into my operating system (Ubuntu 9.10) at which point the second lcd screen loses its signal. I suspect that my os, Ubuntu is not set up to support a second display.
Any ideas if this may be related to inverter or something more serious?
P.S. Thanks for the great site – your instructions on dismantling the DV9000 are extremely useful.
November 7th, 2009 at 6:14 pm
Robert,
Can you still see a very faint image on the screen when it goes black? Look very closely.
November 7th, 2009 at 6:18 pm
Lloyd,
If the laptop works fine with an external monitor, most likely the motherboard/video card is good.
You said the screen works fine at certain angles and most likely this is somehow related to the video cable.
1. The cable could be loose on one end. Try reconnecting the cable on both ends. Reconnect the cable on the motherboard and back of the LCD screen.
2. Could be defective cable. Try replacing it with a new one.
3. There is a chance of bad LCD screen.
This failure is not related to the inverter board. The screen is still bright, so the inverter and backlight lamp work properly.
November 16th, 2009 at 12:44 pm
Dear Laptop Tech,
Thank you very much for your helpful response and for the great tutorials on your site.
As you suspected the problem appears to be a faulty video cable, the video cable has been damaged where the laptop hinges. I have a replacement cable on order and after re assembling the laptop (with the cable in a slightly different position) my problem appears to be temporarily solved.
Although I will be glad once my new cable has arrived and is in place!
Thanks again,
Lloyd

I just had an experience that makes me believe they are designing them to fail. The LCD screen on my HP Presario C700 became intermittent. I opened it all up and found that there was a small circuit board at the bottom of the screen that had exposed terminals right next to a grounding plate. If they touched, the screen lost backlight power. The only solution was to reboot. There was a small, soft buffer to keep these two parts separate, and it that got compressed, the short would happen. Now here’s the weird thing. The grounding plate that creates the short is INTENTIONALLY there. It seems to have no other purpose than to be in close proximity to the charged circuit board. If you wanted to design something that would go out in a few years of use (but beyond the warranty policy), this would be a good way to design it!
November 28th, 2009 at 3:06 pm
Well i have a HP Pavilion dv1000 and for about 6 months now (way past warranty) ive been dealing with colors showing up all over the screen. My situation is very similar to Indy B’s. I also see pink and green but more in fuzzy dots all over. I also see a light blue and red. The light blue shows up where the color is lighter and red is the opposite. I went to get it fixed but the guy only fixed it so when i have it sitting on a flat surface and do not move the screen, does it stay normal. Luckily i only payed 35$. I have no idea why my computer does this or how to fix it completely this time.
November 29th, 2009 at 12:55 pm
Courtney,
You’ll have to test the laptop with video output on the external monitor.
If video on the external monitor works fine and the problem appears only on the laptop screen, most likely it’s either bad video cable or LCD screen failure.
From your description I think it’s related to the video cable but not sure 100%. I would try replacing the video cable first and if it doesn’t help, move to the LCD.
I assume that the guy who “fixed” your laptop tried reseating the video cable connector on the motherboard. If not, try it. It’s possible the video cable is not making good connection with the motherboard.
December 4th, 2009 at 11:10 pm
HP is horrible when it comes to the extended warranty on labtops that are discovered to be defective or lemons after being released on the market. You’d think they do some dogfooding before releasing these lemons.
I called them to see if they would repair/replace my system board for free because my DV9000 was getting a dead display screen on boot and they told me the warranty that had extended because of that known issue had expired 3 months ago. F@%$ing sucks.
December 9th, 2009 at 2:02 pm
Dear Laptop Tech,
I recently replaced my inverter board (Ref. Post #145) as you suggested. The inverter board does work and keeps the backlight on. I am having a pretty big issue though, my battery barely holds a charge and when I transport my laptop, the back light no longer works. It does work again when I unplug the inverter board and plug it back in. Basically it seems to work fine unless the computer’s power is completely drained and attempted to turn on again.
I was curious if you had any suggestions or helpful information. I’d also like to note that when connected to an external monitor, the screen goes black every now and then for short periods of time, sometimes over and over for a minute or so.
December 9th, 2009 at 3:08 pm
This is an update to my post directly below, the back light just shut off on me without draining the battery. I plugged it back in and it’ll work for a while. Any help is greatly appreciated, Thanks -Ryan

Hello,
I have a DV9000 series laptop with screen issues, which I believe is caused from the inverter. The first time, I had my laptop screen replaced by HP (they said they replaced the inverter) but I got a whole new screen. Now a little over a year later, i am getting the same problem. Its been flickering over the past few weeks and going completely black over the past few days. Sometimes it works when i reboot, sometimes it doesn’t. It still turns on (I can see my mouse move with a flashlight held to it).
I called HP and they want to charge 400 bucks for a replacement and 45 bucks for diagnostics (ca-chink ca-chink). The HP guy said inverters have a few year life span, and said it is very rare to get one bad inverter (yet alone two). Do you have any advice what else the problem could be? Is something loose or am I just unlucky?
Thanks in advance!
December 14th, 2009 at 3:46 am
Howdy. I’m having a display issue with my GF’s Presario R3000(intel).
The computer posts and boots windows XP fine with no unexpected shutdowns. When the problem is occuring, it is present at all stages of operation (POST, BIOS screen, windows, safe mode, startup and shutdown).
The problem is this: white colors are replaced with cyan and black areas are partially replaced with diagonal red static patterns. Other colors seem to be affected as well, but are harder to pin down. The cyan/white replacement shows blockiness where white is supposed to be shading into another color.
Tilting and jiggling the monitor has sometimes fixed the problem entirely, and always appears to affect the red/black static. A secondary monitor runs without problems, and sometimes just plugging it in fixes the laptop’s display.
The computer was dropped 2 feet onto carpet while open and running recently, and according to my GF has been dropped in the past. There is no visible damage to the screen or case.
Any ideas what this would be? I’m hoping it’s a problem with the cable to the LCD.
December 20th, 2009 at 11:27 pm
drear laptop tech i was wondering where do i get a replacement screen for my hp pavilion
dv 9000 17″wide screen
December 21st, 2009 at 1:56 pm
dingledinglepop,
There are many different suppliers on the Internet. Just search by the screen part number or laptop model name. Where to get it? It’s up to you.
December 21st, 2009 at 4:36 pm
Ranger W,
1. Try reseating the video cable connectors on the back of the LCD screen and motherboard. Maybe one of the connectors got loose.
2. If reseating the cable doesn’t help, most likely you’ll have to replace the LCD screen.
December 21st, 2009 at 5:05 pm
Thanks for the response. I’ll give it a try.
December 25th, 2009 at 12:15 am
Hi everyone, i seem to have a problem with my laptop… I was playing World of Warcraft last night and all of a sudden while playing, the colors of the game changed purple greenish, and 2 minutes later, the screen turned black, i manually shut the computer down and restarted it, this time there was no image appearing on the screen, but only a faded black image dimm image of the loading screen of windows vista, but that only lasted 2 seconds, then it went back to the black screen. Everytime i restart my laptop, the screen appears to work for like 1.5 seconds, then it dims back to grey then black. I also see grey lines, dots, greyish black everywhere,. Anyone know what this could be?
December 25th, 2009 at 12:20 am
My Laptop is a: HP DV9894CA TL-68
AMD Turion X2-Dualcore 2.1Ghz, Windows Vista 64bit, Geforce 8400M GS, 17inch Widescreen, 4GB Ram, 325gb Hard drive, bought it for 899.99 plus 3 year warranty from future shop.
I cant believe that HP sux at laptops, i guess i should have done more homework before buying a laptop. next time i will go for mac…this is totally oblivious.
I bought it 1.2 years ago, so warranty expired by manufacturer. thats 1 year and 2 months and im having problems already.
December 26th, 2009 at 10:25 am
Hey.
i’ve got a Toshiba satellite 4225 and the laptops’ display works for less than one second when i turn it on.Is there some lose connection or anything that i will be able to fix??
December 26th, 2009 at 12:16 pm
I just wanted all of you to know, I just had to replace my 17 inch screen on my hp and they wanted almost 500$ for it. I went to screentekinc.com and with the no glare upgrade and COD delivery was $186. I love it and it came with instructions. good luck.
December 29th, 2009 at 12:08 pm
how do u fix the blank black screen?
December 29th, 2009 at 12:10 pm
The Irony is that i bought my laptop for 900 dollars about 1.2 years ago, and problem occured right after HP warranty expired!!!!!!!
December 30th, 2009 at 6:55 am
Dearest Laptop Tech:
Are there two separate lights on Pavillion 9000 ?
The left side of the screen is darker on mine, but the right side is well lit.
are the lights replaceable or is a whole new screen needed?
Thanks
December 30th, 2009 at 9:25 am
Mat,
According to the service manual for HP Pavilion dv9000 notebooks, some LCD screens come with dual backlight lamp. Chapter 5.14 here: http://h10032.www1.hp.com/ctg/Manual/c01311536.pdf
The backlight lamp is mounted INSIDE the LCD screen and it’s very hard to remove and replace the faulty lamp. If you’ve never done it before, I would suggest replacing the whole screen.
From your description is sounds like the screen has to be replaced.
December 30th, 2009 at 9:48 am
jajaja,
There is no simple answer. Does your laptop start at all? Can you get image on the external monitor?
If the laptop turns on and makes normal noise, but there is no image on external and internal screens, check the memory module first. One of the memory modules could be bad. Try removing memory one by one. Test the laptop with only one memory module installed.
December 31st, 2009 at 3:15 pm
Well, i was on the internet the other day and all of a sudden color’s on the screen started to change from purple to green, then i got a blank black screen. Tried restarting and the screen re appeared however i can hear the PC start up normally in the back. I restarted roughly 3-4 times and i was able to see a dim image of Microsoft Windows Vista loading in the back but after 1.2 seconds it turned back to greyish lines dots, and black screen again
December 31st, 2009 at 3:17 pm
i dont know what u mean by memory module. Is that the RAM or the HDrive? why would the memory be a problem, looked like a graphical video card error.
January 1st, 2010 at 10:18 am
I have the same series laptop here. My problem is when i go to adjust the lid of my laptop to a different angle. When i adjust the lid, all this green stuff flashes through my screen. I don’t know what the problem is.
http://www.youtube.com/watch?v=8a_WjyOYbGQ
January 3rd, 2010 at 2:02 pm
Willis,
I think it’s either LCD screen failure or bad video cable.
Most likely bad LCD and less likely bad cable.
January 3rd, 2010 at 2:11 pm
jajaja,
I mean the memory module.
Because in one of the previous comments you asked how to fix the blank black screen. You didn’t mention any graying lines dots.
First of all, you’ll have to test your laptop with an external monitor. Can you get the external video to work even though the laptop screen is blank black? Can you get normal image on the external monitor?
If the external video works fine most likely your problem is not related to the memory (RAM) or video card failure. It could be bad video cable or faulty LCD screen.
Let me know if you can get normal image on the external monitor.
January 6th, 2010 at 3:14 pm
My laptop has a completely black screen. It is not dimmed like others where you can see desktop items with direct light from a flashlight or something. Would a new inverter board fix this problem? Or is it a problem with the LCD or GPU? Thanks so much!
January 6th, 2010 at 3:20 pm
Joe,
If there is no image at all, a new inverter board will not fix the problem. Just make sure that the screen has no image because on some screens it’s very hard to see.
Can you get video on the external monitor connected to the VGA port?
If not, try reconnecting memory modules. Remove them one by one and test the laptop with each module separately. This could be memory related problem. Maybe one of the modules has failed.
January 7th, 2010 at 9:08 pm
I have the same problem as Joe, (black screen with no sign of light) and when plugging into vga port with another monitor that monitor is also all black. I tried testing each memory module one at a time and still all black screen. The laptop (hp dv9000) when only one module is inside during the testing seems to try and restart (or tries too). The blue lights turn off then come back on. They stay on but only for about 30 seconds then turn off and on again. When both modules are in the lights stay on but with black screen. Is the screen bad or the cable inside? Thanks for listening.
January 8th, 2010 at 10:59 am
I have a broken laptop similar to above and removed the intact lcd screen, ribbon, and inverter and was wondering if I can turn it into a desktop monitor with a vga cable connection somehow?
January 8th, 2010 at 11:02 am
Chris,
Do you mean connecting the laptop LCD screen to a desktop computer? No, you cannot do that.
January 8th, 2010 at 11:24 am
So is there any use for the parts mentioned without a controller?
January 9th, 2010 at 2:18 pm
i am trying to lubricate or replace the fan on a HP Pavillion dv9700….. any hope or help out there?
January 9th, 2010 at 11:10 pm
I have my LG notebook pc, which have problem of occurance of horizontal coloured line when i tilt or bent the lid of lcd screen the line disappear can you help me what is the problem of my pc?
January 11th, 2010 at 4:24 am
Hi,
my pavilion dv9000 works fine if I don’t open the screen any further than about 60 degrees. Beyond that the screen becomes a mess. Still working but all scramled up. On an external screen the laptop works fine. So it is a screen problem. I already opened it to see if there where any loose connections but i didn’t find any. Anybody any idea which part to blame, replace or how to fix it?
January 11th, 2010 at 4:40 am
I have the same series laptop here, and it doesn’t start, it just shows a black screen, with some lines and gray dots.
When I disconect the lcd`s cable it starts with a external monitor, normaly.
but when I connect the LCD it does not starts.
Should it be a LCD problem or video board problem??
Thank you
January 12th, 2010 at 8:29 am
Hi, I am trying to replace the video cable (dv9000. The part dealing with the LCD screen is well documented but what I am mising is how (where) to disconnect the cable from the mother board. Can you help?
Thanks in advance.

January 15th, 2010 at 11:40 am
Hi
I have a HP DV9000 the screen cable to the motherboard is loose and the pins have got damaged so there is no pictures on screen unless I wobble the connector, it works fine connected to an external monitor. I have tryed to get it fixed put they all say to much hassle to get at the socket on the motherboard, is there any where I can send it or buy a new socket to fit it myself.
Anyone any ideas or help please, I hate the HP DV 9000 but want to fix it to sell it.
January 17th, 2010 at 2:29 pm
Wonderful, detailed instructions.
I had the same issue as a few others where my dv9410 (2.1 yrs old and out of ext warranty) lcd screen would show vericles lines and blankout after I opened the lid past 60 degrees or so.
I followed the directions to removing the bezel and switch cover, and found that the VIDEO CABLE WAS GOING BAD at the bend under the left hinge. I bought some time with the cable by removing the 3 screws INFRONT
January 17th, 2010 at 2:39 pm
OK- I dunno what happened, but my comments just got sent somewhere before I finished…
GREAT INSTRUCTIONS – PERFECT FOR MY REPAIR…
I had the SAME ISSUE as a few others posted here, where my dv9410us LCD SCREEN would show VERTICLE LINES AND BLANKOUT if I opened the lid more than 60 degrees.
I followed these instructions to remove the bezel and switch cover to discover that the VIDEO CABLE WAS GOING BAD at the bend under the left hinge. I bought some more time with this cable by removing the 3 screws INFRONT of the hinge, slightly tilting the lid clockwise, and pulling the cable up a few millimeters past the bad bend. Since the cable works well bent, but breaks open (?) when straightening, I kept the bad spot bent and secured the cable under the hinge a few mm down on a new sopt. The screen NOW WORKS PERFECTLY AT ALL ANGLES!
I could have bought a new video cable for $50 or $60, but I suppose that could wearout in a couple of years, too. We’ll see how long my repair holds up.
January 18th, 2010 at 4:56 pm
Dave N,
Maybe you should try replacing the video cable first. It’s possible that connector on the motherboard is good.
January 19th, 2010 at 4:08 pm
Thanks for your reply, it;s definatley the socket on the motherboard as it has been in for repair and a New screen did not work and the socket on the motherboard has bent pins, Is it possible to replace just the socket, the screen works but faint if I wiggle the cable it shows up fine for a short time. Is there a way to find out how much HP will charge as I can not find a local shop that can fix it, any help will be appreciated.
January 20th, 2010 at 3:08 pm
Thanks for the instructions =] inverter came loose :S poor build quality I guess or maybe me dropping it on the floor…….
January 25th, 2010 at 12:27 pm
I have HP Pavillion dv9000 and when I switch on the screen is bright green. Also flickering and everything, including text, is shadowed with red lines and dots.. My pics are green with lines and tiny white and red pin pricks …. fed up
January 25th, 2010 at 1:38 pm
carole,
You’ll have to test your laptop with video on the external monitor.
If video on the external monitor doesn’t work properly either, most likely there is a problem with the video card (which is integrated into the motherboard).
January 27th, 2010 at 8:28 pm
HI, i have HP PAVILION DV-9700/ VISTA wind/ When i turn laptop on , this is what pops up on the top left corner : “PRESS F1 to continue or F10 TO SETUP”???
This is driving me nuts, how can I remove this F1 ERROR?Every time when I want to go online I HAVE TO CLICK THAT F1 ERROR FIRST? PLEASE HELP

Hi everyone!
I have a problem with my LCD, there is a little hair (2 inches long) on the screen, but cannot be removed because it’s between the LCD and a protective layer (I guess) can anyone help me?
Thanks
January 31st, 2010 at 6:29 pm
hi, i have a dv9267 laptop but im having problems with it, there seems to be something wrong with the screen or maybe something associated with it, when i turn on the laptop the back light of the screen works but it doesn’t display anything, its just blank/black. ive tried using an external monitor and that works fine, the only thing i notice on the external monitor is that the laptop only starts in safe mode and not normal mode if i try starting it in normal mode it turns off, im not sure if this is related to the screen problem or is a separate issue. i don’t think there is a fault with the screen itself as on the off occasion it does start up and display everything as it should be, but then again i could be wrong.
could you help please!!!
thanks
February 2nd, 2010 at 1:19 am
I just got a crack in my hp dv9000 screen top right hand corner that create a bunch of vertical and horizontal lines. The crack is growing and adding more lines. So I’ll have to replace the LCD. Outside the 1 year warranty, are there any service places where I could get the new screen installed relatively quickly and inexpensively?
February 4th, 2010 at 12:56 pm
wow! Very helpful tutorial. Thank you very much. I am a web developer, so I’m great once you turn the computer on, but I’m not so technical on the hardware side of things!
This was very easy to follow and I got it all done within about 10 min.
Thanks!
February 4th, 2010 at 12:57 pm
I wonder, is there anyway I can sell my old LCD screen for my HP DV9000??
It is damaged, it has black ink on the top left, but it technically still works.
Anywhere I can sell this???
February 6th, 2010 at 11:00 am
This helped me out a lot. Thanks for publishing this very easy to follow how to.
February 7th, 2010 at 8:36 pm
Nick Shwaery,
If the LCD screen has a crack, it cannot be repaired. I really doubt that you can get a lot for this screen. I guess someone can buy it for a few bucks if your damaged screen has a good working backlight lamp. Maybe someone needs a new backlight lamp.
February 8th, 2010 at 4:27 pm
I have an HP dv9000 series laptop. It is functional but lately I have noticed a slight distortion when I change the angle of the lid/screen. Is this indicative of a specific problem?
Thanks,
– Matthew Bondy
February 8th, 2010 at 11:04 pm
Matt Bondy,
You’ll have to test your laptop with video on the external monitor.
Connect the monitor and set the laptop to display video externally. Do you get same distortion on the external monitor when you move the laptop lid/screen?
February 16th, 2010 at 11:31 pm
I have this same laptop (HP dv9000 series) . The gpu just fried cause the laptop kept over heating really bad. I wanna know if i can use the lcd from this laptop and find away to use it as an lcd for my psp. what i wanna do is build the lcd and psp into the headboards for my daughters bed, and hard wire a ps2 (which i know how to do that at least) controller, this way my two girls can watch anymovie they want and play any game they want with out fighting over the tv or game systems. i think its a pretty good idea, and i will prolly have to find away to connect the laptop lcd screen to an external power supply, cause i am sure that the psp wont handle the requirements powerwise of the new lcd but it should be able to handle the bigger screen since it is able to be played through the computer with certain software mods and through the tv with other connections. but the goal for me is to rebuild the whole system bigger and better into the headboards of my childrens beds, well footboards anyway. this is my idea and i hope it doesnt get stolen and my name is Crystal Stophlet and the date is 2-17-10.

[...] How to remove LCD screen and inverter board from HP Pavilion dv9000 [...]
March 2nd, 2010 at 8:30 pm
I’m having a weird problem that I’m not positive how to fix. I can’t find someone that has dealt with the same problem specifically. I have a DV9000 and when I move the monitor back the screen goes black, move it forward and it comes on again. It seems to only like certain positions, really favoring the “closed” end of things. Best I can figure is that it is a pinched display cable but i’m not positive. If this is the problem i’m really not sure of the part number I need to order. 432962-001 seems like the right one but I don’t really want to pay 80 bucks for the wrong part. Can you help me out?
Thanks!
March 2nd, 2010 at 10:47 pm
Dustin,
It’s possible that the cable is damaged.
HP Pavilion dv9000 notebooks are known for a problem with the left hinge, that’s where the cable is running.
Take a look at this guide:
http://www.insidemylaptop.com/how-to-replace-broken-left-hinge-in-hp-pavilion-dv9000/
In a case like that, I would remove the screen bezel and keyboard cover. After that turn on the laptop and try moving the cable while the laptop is still running. If moving the cable affects video on the screen, it’s likely the cable is damaged and has to be replaced.
Proceed at your own risk. This is not for beginners.
March 8th, 2010 at 4:33 am
Thanks for the great guide! I’ve started having an issue where half the screen was flicking (Dual lamp Inverter model I’m guessing). Now its just not lighting up at all. I pulled it all apart, gave it a few nudges here and there and it worked again! Problem is I have to do this all the time now. I tried nudging all the cables while its running and can’t get it to flicker so I’m thinking its the lid switch going awry, can you tell me where it is so I can have a look at that, I can’t find it!
Thanks heaps again!

Hi, Thanks for the Great job and a great help you give so many of us. I have a HP ZD81200cl, I have read all the past post on panel problems, mine seam to fit in to many of the discriptions listed. Narrow verticle lines, a line that is vertical and about 2 inches wide that is white on the left side of screen, but after it has been on for a few minutes, slowly disapears and screen is back to normal. I pluged in another monitor (flat panel) I had as you sugest to do, and everything looks great. no lines or white spot.
My question is, My panel is a 17″ LG Philips LCD LP171WX2 (A4) (K1), 1440X900, I am having trouble finding a panel like this but there are many that are LP171WX2 but have a higher resolution. Will the higher resolution work on my computer? My external panel is much phigher resolution than my laptop and it works with no problem, so I take it from that that my video card should have no problem handeling the higher res. Or am I missing something?
Greatly would appreciate your input.
Thanks Serge

Hi, I have an HP Pavilion dv9000 about 2.5 year, and for now the story is not what i like.))
1) The mous pad doesn`t work in about 6-8 monthes, it reacts strangely or it move so sharp and stack or no any moves, what I`ll have to do with that ??
2) First it did fall flat to the ground from 0.5 m, the screen is when laptop is boot up Windows XP, looks burgundy in color the whole screen, after it if I`ll use it for to watch pictures, fotos, the parts of the screen looks burgundy and saturated , and it has a greenish tiny vertical strips at the whole screen.
I went to chek it to computer store when they plug it in to regular monitor it shows the screen working well like a brand new, so please tell me do I`ll really have to replace to the new screen ???!!!
Thanks

Hi, I have a similar connector to that in picture five (5) above (the one with the inverter)
Am I to understand that the picture indicates a 1 CCFL screen type?
Thanks!
