The 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.

@ 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,
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.

@ 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.

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!

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 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.
