HomeThe following video created by Rebootit.biz explains how to fix video failure in HP Pavilion dv2000, dv6000, dv9000 series notebooks.
Video failure is a very common issue with HP Pavilion dv2000, dv6000 and dv9000 series notebooks. It happens because of poor design of the cooling module. The video chip overheats and separates from the motherboard.
VIDEO FAILURE SYMPTOMS:
1. Notebook turns on, all LED lights light up properly but nothing appears on the internal LCD screen. The notebook LCD screen is completely blank and black. Also, there is no video on the external monitor attached to the notebook.
2. Video on the notebook screen and external monitor is garbled.
HP KNOWS ABOUT THIS PROBLEM:
HP knows about this problem with dv2000, dv6000 and dv9000 notebooks. Some qualified models HP fixes at no charge by replacing the motherboard. This offer from HP is over.
Basically you have two options:
1. Replace the whole motherboard with a new one.
2. Fix the failed video chip as it shown on the video.
As an example the author is fixing an HP Pavilion dv9000 notebook but same technique can be used on HP Pavilion dv2000 and dv6000.

For the video chip repair you’ll need aluminum foil, new thermal compound (thermal grease) and hand soldering flame torch.
I haven’t tried this fix myself but according to the video it should work pretty well. Proceed at your own risk! If you are not careful enough, you can permanently damage the motherboard..
UPDATE: here’s another way to tix the failed video chip by baking the motherboard in an conventional oven.

I have the HP Pavilion DV6000. I am having similar problems with my LCD screen. Instead, my screen is “flickering” on and off. What can I do to repair it myself.
March 1st, 2010 at 11:31 am
Terone Hartfield,
How it’s flickering? Is it loosing just the backlight and the data (image) still present on the LCD screen?
It’s possible that your problem is not related to the video chip failure. If the backlight flickers but the image remains on the screen, most likely your problem is related to the inverter board failure.
Did you have a chance to test your laptop with an external monitor. Can you tell if the external video flickers too?
March 1st, 2010 at 3:43 pm
Let’s say you have one of the above mentioned laptop with blank screen.
When you press on the power button, all power LEDs work but there is no image on the screen.’
Before you jump to a conclusion that this problem is related to the video chip failure, try playing with memory modules.
Try reseating memory modules, try removing them one by one and test the laptop with each memory module separately. It’s possible that one of the modules is bad.
March 3rd, 2010 at 12:39 am
When I connect to an external monitor it works just fine. I am able to use my laptop it just blinks literally like 15-20 times a second.
March 3rd, 2010 at 11:09 am
Terone Hartfield,
If this problem appears only on the laptop screen and the external video works fine (without flickering), most likely this is not the video chip failure.
How it blinks?
Do you lose just the light and the data stays on the screen? Or both the backlight and data disappear?
If the screen light flickers but the data remains on the screen all the time, it’s possible you have a faulty inverter board – a power supply for the LCD screen.
Here’s how to access and replace the inverter board in an HP Pavilion dv6000 notebook:
http://www.insidemylaptop.com/remove-replace-lcd-screen-inverter-hp-pavilion-dv6000-laptop/
This is just a guess. It’s very hard to be accurate 100% without even touching the laptop.

A friend of mine has an HP Pavillion dv9700 and his video is garbled as well. I was wondering if his laptop is effected by this problem as well? If it is, I think we will try and fix it ourselves. I’m fairly comfortable around tech and just recently swapped out a busted display in an HP G70. With that in mind, I was wondering what the size and thickness of the copper shim are? That is if the laptop is effected by this problem. Thanks for the video.
March 4th, 2010 at 2:29 pm
Bob,
If the video is garbled on both, the internal LCD and external monitor, this is the graphics card related failure.
But I’m not sure if the above mentioned fix will work in your case. Be careful, you can destroy the motherboard, so do it only as a last resort.
There are many different shops/technicians out there fixing dv2000/dv6000/dv9000 motherboards for about $100. I just added a link to all these offers on eBay in the post.
March 5th, 2010 at 7:24 am
Hi there,
I just watched your video which is very well done by the way. One thing I don’t understand : you put aluminium foil all around the graphic chipset then you heat it with the torch, all right but after that where do the 2 pieces of copper come from, did you cut it yourself?
See I don’t see the connection between heating all around the graphic chip then taking all the alumninium away to put thermal paste then the copper.
Thanks for the explanation.
Mark
March 5th, 2010 at 9:50 am
Mark,
This video was created by http://www.rebootit.biz/ not by me.
Yes, it’s a custom made copper piece. They make it from a copper sheet.
But if the repair is done correctly the laptop should work even without those copper pieces.
The aluminum foil protects all other components on the motherboard from being damaged by the torch. When you heat the graphics chip with torch, you basically melt solder underneath the chip and the chip gets resoldered to the motherboard.
After resoldering the graphics chip, the aluminum foil must be removed.
They put a customer made piece of copper for better graphics chip cooling.
By the way, here’s another fix for video chip in dv2000, dv6000, dv9000 and tx1000 also known as “Penny fix”.
March 11th, 2010 at 6:12 am
Hey, watched your video.
But I might have something different here. This problem appeared yesterday.
I have Pavilion dv6 – 1231 eo
My picture is also flickering a little. But it´s like in certain areas. For certain colors it is different.
For example when I have black background, there is little red sparks flickering all over the screen. Like a movie effect.
Mostly are those red/blue sparks in areas, where one color is going over to another color.
I tried an external monitor and it´s pic is fine.
I remember some automatic updates yesterday just before this problem appeared and I tried to do system restore 2 times to my Vista, just in case. But in didn´t let me do it. it said windows cound not finish, because some problems appeared or something.
I also went alt+F8 when restarting my computer and piced repair from that menu – and what is strange, the flickering was gone. I did nothing there.
Then I restarted my computer again and flickering was gone (almost). There was only a very little area in the middle of my screen with blue sparks.
Then after 2 minutes all the red sparks and flickering was back again.
Any idea where can be the problem?
Thanks.

I have same problem. My client’s can turn on but no display (blank). The Service center said to client that the problem related with power of motherboard. If it wanna service, u must wait until 40 days or but a new one (expensive). The client had canceled it and decided to fix with me. Ok, I try it with the external monitor is not working fine. I think the problem is related with motherboard. I founded some reference on internet and got it. I try the way of internet to blow up the BGA chip with rework station. After that, I turn on the laptop and it running normally. Nice job !!!. Thank’s.
March 15th, 2010 at 12:13 pm
Hello. great video showing the video chip reflow. I have a few of these and this is a well known issue. I do haveone though Im a bit stumped on. It has some kind ofpower issue somewhere. I can plug the power adapter in and get blue lights no issue nothing happens if I press the power button. Now if I put a charged battery in the unit it boots up just fine.Take the battery out it shuts down just the blue lights.Anyone had this issue come up?
March 21st, 2010 at 8:57 am
I have the hp dv9000 and was sitting working one day and the screen just went blank
and started flickering colors across the lcd….turn it on now and only backlight shows
on the lcd but no picture. I plugged in an external monitor but nothing shows on the external
monitor….does this sound like the chip problem from the video????
March 22nd, 2010 at 11:19 am
I have a HP Compaq 6735s it works good but i noticed that if i do not have an external fan cooling the laptop after approx 30 min of running the laptop gets hotter then it should in my opinion and the screen will go black and the only thing i can do is shut it down and reboot i usually have to have a cooling pad running and another fan directly on the pc to prevent it from happening would that be the cooling fan malfunctioning or is it a problem with the video card?
March 23rd, 2010 at 1:38 pm
I can’t believe that I just fixed a dead laptop with a heat gun and a penny! I used a heat gun in place of a torch and shimmed the video chip with a penny. Loading windows right now! Thanks for the great tutorial!
March 23rd, 2010 at 4:10 pm
Hi, I have an hp pavilion entertainment dv9700 laptop. A few weeks back my computer would only show a white screen which over a 30 second period became a screen of blue and black bars. I tried reseating the ram, hard drive and all that but it didn’t seem to work. When i connect to an external monitor it nothing shows up. I was wondering if this was also due to the video card failure. I bought mine back in august of 2008. Hp said I wouldn’t be covered since it was past the 1 year warranty. Also any suggestions on what i should do?
March 24th, 2010 at 11:43 pm
I just happened to stumble on to this web site cause my compaq has overheating problems…what a great web site…keep up the good work!!! ps. I love the videos!!!
March 30th, 2010 at 11:55 pm
Hi
From Sweden
Watched your video abt heating the video chip,
Will it work on for example HP NC6220 and
6715B also , I have some of them laying here
with most probably faulty video chips.
Thks
March 31st, 2010 at 10:35 am
Kjell,
I don’t know. You can try if you have nothing to lose.
I think tomorrow I’ll try to fix a motherboard from a Compaq Presario v6000 notebook by baking it in a conventional oven (385 degrees Fahrenheit for 8 minutes).
April 1st, 2010 at 1:02 pm
Scott Choy,
If you cannot get video on the external monitor either, probably this is the graphics card problem.
The graphics chip is soldered to the motherboard and when it fails, the whole motherboard has to be replaced or repaired.
April 1st, 2010 at 1:27 pm
Brian Foresman,
Take a look inside the heatsink and cooling fan. Maybe the cooling module is clogged with dust and has to be cleaned up.
It’s possible the laptop loses video because of overheating.
Clean the cooling module and test the laptop without the cooling pad again.
April 1st, 2010 at 1:35 pm
gary,
Yes, this description does sound like the video card failure.
April 2nd, 2010 at 2:34 am
i’m wondering if it work with sony vaio vgn-fe25gp i have a symptoms #1. Notebook turns on, all LED lights light up properly but nothing appears on the internal LCD screen. The notebook LCD screen is completely blank and black. Also, there is no video on the external monitor attached to the notebook.
i opened my laptop and i found my video chips has a bubble around it .
i have a question if i have to heat my video chips?
do heating my video chips work with my sony vgn-fe25gp?
please reply with my problem does anyone know what should i do?
April 2nd, 2010 at 2:36 am
thanks in advance
April 2nd, 2010 at 3:27 pm
cherrynele,
Maybe you have a failed memory module? Have you tried replacing the memory module?
If you have two memory modules installed, try removing them one by one and test the laptop with each memory module separately.
Also, try disconnecting the CMOS battery, wait for a few minutes, plug the battery back in and try turning the laptop on. This trick helped me a few times before with Sony laptops.
Not sure what you are talking about. On some motherboards the GPU can be glued to the motherboard.
April 3rd, 2010 at 2:14 am
from the start i thought it was the backlight of the lcd then i replace ccfl bulb of it then i try to turn it on . the display on the lcd was garbled and still does not have a video on external monitor connected to pc. i try disconnecting a CMOS battery for a few minutes , replacing each memory module one by one but still there no video detected on a external monitor and garbled on lcd monitor. it has only its start up sounds clearly.
and i found that my video chip has a bubbled like your video shows do you think i have to heat my video chips to get connected to my mother board?
and how do i know if my video chips are not connected to my mother board any other symptoms?
any ideas to my vaio VGN-fe25gp problem?
lots of thanks to you in advance.
April 3rd, 2010 at 1:16 pm
I have a problem wih my HP Pavilion dv7-1070ei laptop display. when i boot the pc all i see is just a black display, there is however some faint images on the screen that suggests that my display is fine and the problem could be the display backlight. I replaced the LCD inverter and that did not solve the problem, i then replaced the LCD screen thinking that the CFL bulbs are blown. That also did not help, i replaced the cable that connects the display to the motherboard and still the problem was not solved. However, when i connect my pc to an external display, the external display works fine.
I have updated my display drivers to the latest and still no success. my laptop is using NVIDIA GeForce 9600M GT graphics. I then tried my display on a different motherbord and it works fine.
The only conclusion that i have come to is that, my motherboard is not turning the display CFL ON. I also noticed that when i pass a magnet over the switchboard just above the LEDs the display actually blinks and goes dark again. when it blinks i can actually see the desktop icons. How do i solve this problem?
April 5th, 2010 at 2:03 am
Just wondering if his will fix flickering and everythin thats displayed a certain shade of black is showing red? the HP loading screen is very red lol.
Thanks

Hello,
Do you or anyone in the Chicagoland area you can recomend do this job on my Pavillion dv2000 I have gigantic hands and have a very hard tim working with small parts,I am 10 min.
from downtown Chicago and if you know anyone semireasonabe to do this job can you please give them my email and my name.
Thank you,
Dylan Caamano
P.S. I paid close to $1000 for this L/T and so far replaced the screen I beleive because of the high heat this generates(screen just cracked) also battery pack got red hot from purchase and sent me same batt. when in warrenty and these only hold charge for 20 min no matter how long you charge them and I also bought my own battery pack after warrenty expired,I never had such bad luck with a HP but will NEVER buy ONE agsin,I want to get this going it is a vista home preim. strike 2 and out of 14 months I would say I got 8 months use out of it.Thanks again
April 5th, 2010 at 3:13 pm
A quick question regarding to the video:
How can you be sure about the temperature? I haven’t seen any unit to measure the temperature.
Do you use an infrared thermometer? Are there other options (as I do not have one)?
Thanks, Florian.
April 6th, 2010 at 7:21 pm
[...] Here’s another way to fix the failed video chip with a hand torch. [...]
April 9th, 2010 at 1:01 pm
I have the DV2000 and it recently started some strange behavior. The backlight goes out after a few seconds; sometimes I can get all the way into Windows, sometimes it goes out during the boot. Closing the laptop and opening it back up would bring the screen on for another few seconds but it would dim to almost no image again. I removed the lid switch because it’s often a problem with these I guess. Problem didn’t go away and now I can’t close the lid and open it to get the screen back temporarily. I’ve tried the removing battery and power and hard reset tricks, but they haven’t worked. The computer is running perfectly and outputs to an external monitor and I know the backlight and inverter work, but they may be compromised. I guess I’m going to try and update the BIOS and reseat the RAM again, but I guess maybe it’s an inverter or more likely a backlight problem? I heard that the backlight can turn off the inverter if it’s failing to prevent further damage. I read about the GPU issues with this mobo, but since the picture looks good when I can get it to display and the external looks fine, I can’t see how the GPU could be the issue. Thoughts?
April 9th, 2010 at 1:30 pm
Mike Squires,
Sounds like this is inverter or backlight lamp failure. I would try replacing the inverter board first.
How do you know? You cannot test the inverter board or backlight lamp with video output on the external monitor.
Most likely this will not help. Updating the BIOS might help in some cases, but reseating memory will not help for sure.
Most likely yes. It’s either bad inverter or backlight lamp. You eliminated the lid close switch already.
I really doubt that your problem is related to the GPU failure because the laptop still works with the external monitor.
April 11th, 2010 at 10:09 am
I never saw the info on the class action law suit with hp on the dv6000?
April 23rd, 2010 at 9:17 am
I must have missed something: how was it determined that the lid actuator switch was not the problem? I have a dv6000 that shows faint images. If i close the lid for a second, the display will function – sometimes for as long as a minute or 2. I’ve seen “fixes” which entail disabling the lid actuator, but I’m not sure where it is on the 6000 and how many pieces I have to remove to get to it and unplug it.
If anyone can tell me, I’d appreciate it. HP wants $400.00 to fix it for me. Fat chance…….
April 23rd, 2010 at 9:24 am
Devon,
Most likely it’s either bad inverter board or faulty backlight lamp inside the LCD screen.
I would try replacing the screen inverter board first and if the problem is still there, replace the LCD screen (the backlight lamp is part of the screen).
Here’s display disassembly guide for HP Pavilion dv6000 series:
http://www.insidemylaptop.com/remove-replace-lcd-screen-inverter-hp-pavilion-dv6000-laptop/
I don’t think that the lid close switch can be unplugged in this model. I believe this model has a bulit-in magnetic switch activated by a small magnet located inside the display panel.
I don’t think the lid close switch is your problem. If the switch fails, the laptop loses backlight completely but in your case you can make it work for a while if you close/open the screen.
Most likely this is just a bad inverter board.
April 26th, 2010 at 6:51 am
I have an HP Pavillion dv9000 laptop.
The pixels that should appear as black are appearing as a neon green. If I close the screen so that it’s within a few inches of the keyboard, the problems seems to disappear but it reappears when I move it up a bit. I did take apart the bezel over the LCD secreen and checked the inverter connections and the wires going into the laptop keyboard area. I can see the point where it changes back and forth as I move the screen closer and then away from the keyboard, but can’t see any wires or anything that are impacted when I do this.
Secondly, the screen is dimmer than on my other laptop that I own by quite a bit. It’s certainly readable, but it is dimmer than I think it should be.
Finally, the function F7 and F8 which control the brightness of the screen aren’t functioning.
Any ideas?
April 28th, 2010 at 5:21 pm
hi, i hope it’s not too late for me to ask now
basically, i have the same problem with my dv6000. But i wanna ask if mine could some how be different. So i turn power on, no thing appear on the monitor, just black like when there is no power but all the lights on the keyboard and hard drive light work normally. Then there are 2 beeps coming from the laptop. I watched the video and did not hear it in there. Could you answer my question as soon as possible?
Thanks and I ask all the ways from Finland, northen Europe
Tri Thai
May 12th, 2010 at 3:35 am
I my self would merely like to know if 2 very faint beeps on boot is normal for these dv2000 notebooks.
Cannot hear the Vista chime when booting up.
It has power to all the componants including all lights on the keyboard are lit up & no blinking.
hdd lite on frt. blinks 3 times & then go out.
Tried a external hdd kit to access the hdd (with hdd out of laptop) & the hdd will not spin up, but used to until now.
Hdd gets pretty warm.
Did get all the docs & settings on a cd for future recovery procedure in case the hdd as gone south now (possibly).
Thank’s for any comments.
David
May 16th, 2010 at 9:47 am
David B. Vaupel,
It’s not normal. There shouldn’t be any beeps.
Do you get any video on the screen at all?
Remove the hard drive. Try booting the laptop with the hard drive removed.
Probably the hard drive is dead.
May 20th, 2010 at 11:32 pm
hi, i hope it’s not too late for me to ask now
i have problem with my dv6000. I want to know what is the problem. I have 2 problems.
1. My wireless was not detected. I have unplug/plug and install is driver but its still not workout.
2. Then my laptop don’t want to boot. when i turn power on nothing appear on the monitor, just black like when there is no power but all the lights on the keyboard and hard drive light work normally. No beep sound appeared.
Thanks
May 21st, 2010 at 7:24 am
chairiman66,
Sounds like a known motherboard failure. Take a look at this HP page.
No video and wireless card failure are two of the symptoms.
June 4th, 2010 at 1:10 pm
Wow – I feel like my computer is having a very similiar problem, however I’m not so sure. I had suspected my cpu was overheating but I was monitoring temperature while watching a video.. and my laptop froze at 30 degrees celsius (CPU). That was a revelation. The way my mother board is set up is the gpu is the last thing touching the heatsink.. so it goes, fan blows off the heatsink, the heatsink covers 2 components which I don’t know what they are, the HS then covers my cpu where it is screwed down around it – then it covers the GPU.
I have a HP DV7-1135nr
Here’s whats been happening. I start the computer and it will run usually quite a while if I play no video. If I play video – after 15-25 minutes the screen will freeze. The computer does not reboot. If I leave it frozen after about 5 minutes, the screen will flicker and go out. Laptop stays on. On nextboot, I might make it to the windows 7 loading screen, it freezes same thing, next boot it freezes at bios and usually after it doesn’t even come on (the screen) however LEDs are still lit. I have taken apart this laptop so many times, reapplying thermal grease to both the CPU and GPU every single time. This issue has really stumped me. However, I’m in Afghanistan, I have no access to streaming media so I can’t watch those videos and nor do I have an oven. I do have all kinds of equipment for working on circuit cards, motherboards – all things electronics.
If you understand this problem and think that it’s something I can fix or need to know a few more details – I would much appreciate the help. My email is robnadeau13 AT gmail DOT com

Hi,
I am looking for a How to replace video card from my Sony Vaio VGN-SZ series. Do you have any instructions or help for it? I search your website and could not find anything. Could you email me and let me know if you have it?
Thank you
TN
June 6th, 2010 at 6:44 pm
TN,
First of all, you’ll have to find out if your laptop has integrated video card (impeded into the motherboard).
Most laptops have integrated video card which cannot be separated from the motherboard. If the video card fails, the whole motherboard has to be replaced.
Here are partial laptop disassemble instructions:
http://www.insidemylaptop.com/how-take-apart-sony-vaio-vgn-sz-series-laptop/
June 6th, 2010 at 8:02 pm
RobBanks,
Could be memory failure. Maybe one of the modules fails at high temperatures.
Try removing memory modules one by one and test the laptop with only one module (either one) installed.
If the laptop fails with either memory module in either slot, most likely this is motherboard failure.
June 7th, 2010 at 1:35 pm
So this GPU fix wont help me? I’m pretty confident its a GPU problem because the picture goes out. However – possible evidence against this is that when I was watching a movie the screen went out.. but the sound stopped as well? So that’s likely motherboard right? I’m gonna try the ram and I’ll let you know the results.
June 12th, 2010 at 9:54 am
Hey all,
Just another *WIN* for the dead laptop video using the “regular-oven-as-reflow-oven” trick. I got this tip from another website and I have no idea what engineer first suggested it, but I’m posting my success on every site I can as support for those afraid to try it – remember, if your warranty is gone, and you’ve already tried begging your manufacturer to replace it, what do you have to lose? Your choices are: pay someone else, buy a new mobo (if still stocked) or scrapping the laptop.
The laptop in question is an Asus with one of the infamous nVidia 8600m GT with the improperly balled BGAs with insanely high failure rates for Apple, Toshiba, HP / Compaq, etc. that installed them.
Just be vigilant in removing /everything/ from the mobo. If you did well with removing every tiny bit of tape and plastics, you will get no smoke and (nearly) no smell. If not, you’ll know very shortly.
Good luck!
June 14th, 2010 at 7:40 pm
I have a HP dv9000 and right after the warrenty ran out I got the video card nightmare. Of course HP wasn’t willing to help me out unless I wanted to pay them 478.00 bucks. Yeah, like I didnt spend enough on a laptop that took a crap not even 2 yrs after I bought it. So i ordered a new motherboard & took the laptop apart, replaced the mb, put it all back together & turned it on and the blue lights go on & just kinda flash then go right back off. I know everything was put back exactly as it was, but I can’t figure out what could be causing this. PLEASE help me..
t
June 17th, 2010 at 3:39 pm
I have a DV9000 17″. The screen starts to change color until you hold some pressure on it by pulling it. While holding tension on it the screen goes back to normal. IS it the whole screen going bad or is there a cable issue.
June 21st, 2010 at 2:42 pm
Hey Julie Garcia !!
I have a Presario notebook & it also has encountered the video failure problem.I dont know what to do..By the way, did you try extending the warranty using some pack?? coz that would be much cheaper. And how much cost did incur on a new m/b?? Pls reply.
June 24th, 2010 at 2:12 am
Chris Culler, I have same, equip, and same problem as yours, turns bluish at larger angles, I removed the bezel using this awesome websites’ instructions , as it was out of warranty, and found that the video cable is getting worn through. (lower left hinge-video, microphone, and inveter). The cable should have been placed in conduit or at least some sorta bushing through the Plastic hinge area. You will see the back of display(top cover) cuts into the cable when you open lid over a 60°. I checked the Manual i found, via this website also, and parts list does not show any such component, so this does not appear to be an assemly error, but it is so obvious that the cables WILL get damaged eventually, that I find it hard to be a design oversight
Also inspect cables on right side (inverter and camera) i see obvious wear on camera cable, although I never use
I am taking mine down to HP to have them replace free of charge and give a lifetime warrany on these.
Thanks to http://www.insidemylaptop.com !! ( do you take paypal donations?)
Dave
July 25th, 2010 at 3:20 pm
I have a dv9207us and have experienced both the failed video chip and the parted hinge. I am replacing this with a dv7 3173 and I wonder what problem to expect with this one.
I sent it out to New York and had it repaired for $125 (Video problem).
Any ideas/comments about the dv7?
July 28th, 2010 at 9:09 pm
RobBanks,
It’s hard to tell without testing the laptop. Can you get any image on the external monitor?
July 28th, 2010 at 9:21 pm
Bill Paxton,
I agree. If you have no other option, try this method. It might work for you.
I guess this trick works not just for HP laptop.
July 28th, 2010 at 9:23 pm
Julie Garcia,
There is no way I can help you over the Internet. I don’t know if the laptop is assembled correctly. First of all, you’ll have to check all internal connections.

Chris Culler,
Hard to tell. Most likely it’s either bad video cable or LCD screen failure.
Here’s what you can try.
Remove the keyboard/power button cover so you can access with video cable.
Turn on the laptop an try moving the cable, not the screen.
If moving the video cable affects video on the screen, most likely you have a faulty cable.
If moving the video cable doesn’t affect image on the screen at all, an you have to move the screen itself in order to the the image back to normal, most likely you have a faulty screen.

Got the garbled video and trying to view the video, but says its private. Someone please point me in the right direction.

bbush,
Sorry man, I think I should find another video and replace this one.
It was working fine for a few month, but after that the owner disabled the video for some reason. :/
Why would he upload it on YouTube and later make it private??? I have no idea.

Thanks for the info – I’ve been looking for other videos myself. If you find anything decent, please let me know.

I have a v2000 (v2508wm). Laptop screen is black. No images when I shine a flashlight on it. Hooked it up externally and it shows up. Replaced LCD (with new one) and inverter board (new one). Still nothing on laptop screen. Could it be the LCD cable? LCD screen defective? I am running out of ideas..

JayBee,
HP Pavilion dv2000 has a lid close switch hidden under the right hinge. If the switch gets stuck, the laptop will turn on but without backlight. I’ve seen it happening before and first time it took me forever to figure out what was wrong.
Maybe your laptop also has a switch under the right hinge. Check it out. Make sure the switch moves freely.

Video problems are not always hardware problems. Sometime when the wrong device drivers are loaded or if the driver software gets corrupted. Sometimes when the memory is too low because of software overload or virus resides in the memory. If it is a hardware in fact then one is checka memory failure first, most laptops get their video memory form the main memory. Then it could be the video card(built in) , or the LCD light, or the high voltage light supply (inverter) or the lcd itself which is more often the least case.

I have a dv-6xxx (forget the actual model number) and am simultaneously mad and relieved that at the very least I am not alone. I too have a dead-screen pavillion. It’s nearly two and a half years old now.
We were watching a streaming video and then the screen went all scrambled (like when a video card overheated in a desktop I had once) then black and would not turn on again. (However the blue lights all light up and the fan starts).
Actually the problem began to happen intermittently a year ago, the laptop would attempt to start up but then stalled out — over and over again. I became so frustrated at one point that I started giving it love taps (as I had read that the startup problem was a question of loose connection between the video and MOB)… and that actually helped!
For a while.
There was a lot of talk about a class action lawsuit concerning the overheating issue, but have had a hard time finding it onling (HP is unsurprisingly censoring all mention of the issue and suit on their forum).
Does anyone have info about the class action suit?
I am hesitant to bust open the laptop because I don’t have any experience doing that sort of thing and because I have giant, clumsy hands.

It works for me. But one week later happened the same issue. I did the fix again and for now it is working. I don’t know but i think that soon the issue will happen again :/

I have an HP Pavillion DV6910us with a blank screen (the backlight works). An attached external monitor works fine. I have replaced the inverter, the display panel, and the display cable. I have pressed down on the cable connection to the MB in case it was loose. Video drivers and BIOS are current.
I’m not sure if this is relevant, but a while ago the laptop started failing to come out of hibernation, so the user (my daughter) would just remove the battery to force a shut down. This was done many, many times. I suppose something in the operating system or a driver could have been corrupted by doing this so many times, but start-up occurs without problems, it’s just that the laptop display is blank.
Any ideas about what can be causing this problem?
Thanks for you help!

@ TomR,
If you’ve replaced LCD, inverter and cable but it didn’t fix the problem, it must be some kind of motherboard issue. I don’t know what else can cause a problem like that.
I assume your new parts are good working parts.

Hi,
I have HP DV9000 and somthing has gone wrong with the video display. When I turn it ON, there are so many red lines all over the laptop screen
I tried to plug external display using VGA and it works perfectly well on external screen. What could be worng with the laptop?
Video Card? – Could not be this because it workds fine on external monitor
Motherboard? – Could not be this because it workds fine on external monitor
LED Screen?
LED Screen Cable?
Has anyone else had this problem and how did you fix this?
Thanks in advance for the help.

@ Anup,
Most likely you are correct. It doesn’t sound like motherboard or video card failure.
It could be one of the following: bad connection, bad cable, bad LCD. Which one is failing? Hard to tell without spare parts.
Here’s what you can try.
1. Try reseating video cable connector on the motherboard. It’s located under the keyboard cover close to the left hinge.
2. Try moving the video cable while the laptop is turned on. If moving the cable affect image on the screen in any way, most likely you have a problem with the cable. Replace the cable.
3. If moving the cable doesn’t affect image at all, this could be bad LCD screen. Try replacing the screen.

Hi Laptop Tech,
Thank you for really really SUPER FAST reply
this site is amazing 
To my above problem, i ordered new video cable which links from motherboard to inverter and lcd screen. It only costed me £11.35
the guide on this site helped me alot on how to open the laptop. I took the old cable out and placed new cable. I turned on the laptop but was still getting red line but after few restarts everything worked ok
my laptop is all working again thanks to “insidemylaptop” . I’m very thankfull to you all 
If someelse has same problem as me, just replace the video cable
only £11.35 from eBay
