In the past few months, my iBook screen has developed a quite annoying bright "spot" near the middle of the screen. I have no idea what caused it in the first place, but I'm sure it wasn't there when I first got my iBook. The bright "spot" is basically a short vertical line, which vaguely resembles an exclamation mark. It's clearly visible when the area behind it is white. I have the latest rev 12" iBook, and it's still under warranty. But the problem is, there doesn't seem to be an Apple service center in the area I'm living in. So what do you suggest I do?
