The screen on my M460E goes blue with two black lines through it. What could it be, video card problems?

I work for the IT dept of a school district - we have thousands of 460 laptops.
When lines appear it's either the dislay (lid) or the display cable that plugs into the mother board. If you can't find a new display cheap on Ebay, then I'd get a new machine since repairing that would probably exceed the machines value.
When the video goes out on the motherboard of that model, it'll have a black un-lit display with all of the lights functioing fine.

On any model laptop, if you can plug a normal monitor into the VGA plug on the laptop (blue plug usually on the back) & see everything fine on the monitor, then it's definitly the display (lid) & not the motherboard since the VGA is part of the video component.

I did notice yesterday people advertising on Ebay that they can fix displays & mothebrorads but I've no idea how reputable or what kind of warrenty they put on their work.

Hi,

Yes this indicates that your video card has gone bad and would need to be replaced. Sadly, the whole mother board would have to be replaced. Hope I helped
