Please take a moment to look at this display problem video on a PowerBook G4 I had tried fixing for a friend. I had fixed the screen by calibrating the LCD settings, but once World of Warcraft was launched on the laptop, this happened. It is the second time this error has occurred. I have NO IDEA how to fix it. I have tried the calibration again, but had no luck. Even that, it was nearly impossible to see anything since the display is so messed up. http://img531.imageshack.us/my.php?image=pbvid6166945vs8.flv I have tried reinstalling Leopard, but when it prompts me to restart, the disc pops out and it takes me back to the desktop, with no changes. I have no idea how to fix this. I know it isn't likely to be a hardware problem. But I did notice this happens when WoW is attempted to be played. By the way, this old laptop has no running warranty or AppleCare. Need advice.
