I'll begin this by saying this: I've been very silly indeed. Soon after I first bought my Powerbook 15" (the day they came out) the rumours page was chocked with stuff about the strange white patches (this isn't dead pixels) on the screen. People sent them back, only to have the problem return. It was, it transpired, something wrong with Apple's design that applied pressure to the screen from behind. Anyway, I never did get it fixed, even when Apple had solved it, and now it's out of guarntee. The effect, however, is much worse than it was, and I'd like it repaired. I imagine I'd have to pay, but does anyone know how much? Have you had a 15" display replaced?
