Laptop LCD + Green vertical lines

Specs: Vista Ultimate, 1.66/2
Hi,

For some reason my laptop LCD starting showing green pixelated vertical lines allover the screen. I connected an external monitor and it looks fine.

I have tried reseating the video cable on the motherboard, tried to remove static, adjusted the cable in case it was getting pinched too much but nothing seems to remove the problem.

It is clear that video card is fine but can you please help me if this can be fixed and how or if this means usually something has given up ( video cable or LCD )?

Thank You!!

From my experience this is usually caused by the LCD panel. If you decide to replace it make sure you don't over tighten the screws on the bezel or those holding the frame in place. The plastic threads are very weak on this model!

I cannot believe this is happening to me...I believed the laptop LCD or the cable is the cause and I went and replaced the whole display unit worth $300 from ebay...It worked fine for few days and now the problem is back again!

Now it is most likely the video card or the motherboard that is causing the issue and could be overheating...But what I am not able to understand is if it is video card getting over heated or bad, then how come my external display looks absolutely fine?

Can someone pls help me understand if it is video card or something else and why my external display still looks fine?

Also the issue is intermittent, the display corrects itself and looks fine without me doing anything and after sometime it goes fuzzy again by itself.

Thank You!!

These machines do not have separate graphics card, like most laptops the graphics 'card' is integrated into the motherboard.
This model is also known to have a problem with the graphics chip thanks to an nVidia production problem. However the failure of the graphics chip in all cases I've seen effects both internal and external displays. In some cases it stops the computer booting at all!
Is this problem EXACTLY as it was with old display? If not you may have been sold faulty display.
