HP Pavilion dv5-1002nr display problem - Red Moving Pixels on Screen

My laptop is three years old this coming August... I have been experiencing the problem since October of 2009... I have read many posts but I want a sufficient answer in regards to my computer model on how to resolve it...
*Also my warranty is expired (of course)...


Problem via JPEG:



Problem(s):

1. When I turn on the computer, it starts up and shows the red moving pixels, sort of like ants marching...
2. Frequently, my computer will randomly go to a blank screen when I am using it...
3. I have to boot it on after repeatingly turning it on and off... -- the num lk and caps lock lights blink once, every couple of seconds... but doesn't do anything else... so again I turn it off and on...

*As far as my computer goes, it was bought with Windows Vista Premium but currently has Windows 7 Professional....
*It is using AMD Radeon 3200 Graphics...


Please post any helpful tips to fix or temporarily fix this problem...

 

I got the same issue and i am now investigating it.

Did you ever find out the cause of the issue ?

 

I have not solved the issue, what have you found out?

 

My first laptop was a dv5-1004nr. I experienced a display issue that's not too different from this. I would get lines going horizontally from edge-to-edge on my display. My computer was under warranty at the time and the display cable (connects the display to the motherboard) was replaced by HP. You can find those cables on ebay for cheap. That's where I'd start first because replacing the display is a lot more costly.

I'm not 100% sure but I think what happens is the display cable gets pinched or damaged over time from the lid hinges opening and closing.

 

True, but I don't want to pump money into unless it'll fix the issue. Also to add, currently the laptop is beside me... and when I turn it on it won't boot and caps lock + num lk blink once, repeatedly.

 

Could indicate GPU failure. Those AMD Radeon 3200s have a high failure rate. You can't replace the GPU as it is soldered onto the board. You have to replace the entire motherboard. Or you can bake it to reflow the solder under the GPU chip.

There really is no way to completely narrow down the issue. You're going to have to decide to spend money replacing parts (at a minimum LCD cable and/or motherboard) or get a new computer. If parts are going to cost you say $200, you might as well get a new computer in the $400-$600 range with current gen Intel integrated graphics which will perform better than the AMD 3200 and run cooler.

 

Thanks for the information! Since this post, I did in fact by a new laptop. I bought an HP G62 with i3 Intel, and works great! How does baking the board work, and is that safe?

 

Or buy a heat gun and heat the GPU like how some people have had to repair a YLOD'd PS3 (I've done two in the past). Google it.
