iBook shows dozens of "dead" pixels on the screen
Hi! I've got a 12" iBook G4 1.2GHZ that has some odd pixellation on the screen...parts of the screen almost glimmer as if there was glitter reflecting in the light. I've swapped the screen, and same thing. Tried external video, same thing on the external display. PMU and PRAM, re-image the laptop, resolution and color depth changes, and it stays the same. Due to the defect showing up on the external display, I take it the problem is with the board/video chip. However, I'm intrigued because the bad pixels and pixellated areas are 100% consistently in the same place at all times, and they never move or change. I've found that video issues usually involve random elements and constantly changing defects, but this machine is totally consistent, and totally reliable other than that the screen has this situation going on. Any ideas? Thanks!
Is this a good question?
