Green vertical lines on my toshiba qosmio f10 (by 3 users)

Qosimo G35 did the same thing. Thin green vertical line in the center of my screen. It happened after I put my puter in the case without powering it down for a few days. But, I also had a damp usb cable for a camera I had just brought back from a camp trip and pluged in (same time I got it out of it's prolonged stay in the case). Thats when it happened. I cant imagine either of these being the problem since it powers down on battery and the usb cable was damp at best. Oh, my video out crapped out as well so Im pretty sure no software updates, reboots, rebuilds or otherwise will repair this. It is 2 years old and lived out it's term in terms of modern utilities.
