My lcd screen has some issues. It’s kind of hard to explain, so I made a video of it.

As you can see in the video, when I apply pressure, the screen is ok. Sometimes when I remove the pressure afterwards the screen stays ok, but mosty after a while it starts acting funny again.

It looks like you might have a problem with one of the following:
1. Bad connection between the video cable and motherboard or LCD screen.
2. Failed video cable.
3. Failed LCD screen.

For some reason I think this is failing LCD screen. Here’s what you can try.
1. Disassemble the display panel and try moving the video cable while the laptop is running. If moving the cable affects image on the screen somehow, probably it’s cable related issue. You can try reseating cable connectors on both ends or try replacing the cable.
2. If moving the cable (without moving the screen) doesn’t affect image at all. But when you start moving the screen itself the video changes, probably it’s bad screen.

First of all, thanks for the clear step-by-step manual. I’ll make good use out of it when I’ll try to repair my laptop.

I have a question. My lcd screen has some issues. It’s kind of hard to explain, so I made a video of it.

I saw a LCD cable on ebay. Could that part maybe fix my laptop or must I replace the entire LCD screen?

Thanks so far!

You are correct with respect to the graphics output to a external monitor, it corrupts in the same manor.

I’ll look for the specific part number, but my cursory search confirms your suspicion regarding the price of the cards..

Thanks again for your advice.

Best Regards.

I am having some graphics problems with my laptop (compaq 8710w), these comprise rectangluar artifacts across the screen, intermittant flickering and frequent screen freeze and crash. It’s all very frustrating as you can imagine; in your experience do these symptons sound familiar to anyone?

This could be the graphics card failure. I assume you having the same issue with video on the external screen?

are replacement graphics adaptors readily available?

They are available but not cheap. When you remove the keyboard, you should see the graphics card. There should be a label with the part number.
Something like 451377-001 (could be different). Search for a new replacement card using HP part number.

I’m assuming that these issies are graphics card related and therefore plan to take a look to see if there is anything obviously wrong, your guide provides an excellent step by step precedure which I shall be following soon.

finally, are replacement graphics adaptors readily available?

much appreciated,

I have a HP compaq nx6325 laptop which is almost identical to this. I was wondering if it was possible to change the 128mb graphics for a 256mb card or would there be some sort of compatibility or power issues?

I don’t thin you can replace the video card at all.
I believe the video card is part of the motherboard.
If you looks at the HP Compaq nx6325 specs, you’ll see it’s using shared video memory.

i am confused about one thing in hp 8510p laptop if you see down the screen there is a big hp write. on the left side of hp there is a glass hole present.
what is this? and what its uses

Probably this is screen auto-brightness sensor. It dims the screen in a dark environment and brightens it when you are in an area with lots of light.
