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.

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.

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

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?

… 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.

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.

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.

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

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!!

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.

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.

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.

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 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!

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.

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.

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?

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?

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.

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

David Francis,
This site is for anyone who can read.
I’m not really sure what you are asking about. What is your question?
August 6th, 2009 at 2:22 pm
Hi Laptop Tech
Is this site only for the USA? I have three nephews (2 born & USA citizenship!) there. Does this qualify me?
What am I doing wrong? Am I just impatient? Please tell me as I hate to offend!

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
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!
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

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 23rd, 2009 at 9:52 am
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.

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.
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?
