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

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

@ Anup,

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 wrong 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?

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.

@ 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 :/

Mark in Helsinki,

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?

Check out this link: http://www.nvidiasettlement.com/index.html
Search for your laptop in the Affected Models in the left sidebar.
Hope it helps.

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.

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.
