Thanks to the OP and H&L for creating this thread and providing those links. My MacBook Pro's LCD has seen better days. The screen has a bunch of coloured lines running vertically on the extreme left hand sign of the screen. It started happening outside the warranty period so I figured I was screwed. I'm going to look into it a bit more but this thread has given me the courage to perhaps try fixing it on my own.
My screen looks sort of like this but the lines are only on the extreme left.
