I have a problem with my MacBook Pro's screen - here's a video: http://yfrog.com/4wm63z
For those who prefer words, if you divide the screen vertically into 4 columns, the second column is corrupted (flickering, and discoloured, usually with yellow).
I took it to an Apple store and they said it could be the screen or the logic board, neither of which will be cheap to replace.
However, occasionally this problem will completely go away. So before I part with my cash, or decide to turn this into an overpriced media center for my TV... could the problem be a loose cable, or something else cheaper to fix?
