Q: Powerbook G4 screen is blank but backlight still works?
Left my Powerbook open, on and unplugged a week ago which obviously caused to the sleep and eventually drained the battery. Now when I try to turn it on, I hear the chime, hear the hard drive run but the screen remains blank. After a couple minutes though, the screen will flash half white and you can see the backlight turn on from the keyboard and corners of the screen. I can change the brightness, change the volume, everything - the screen will just not display any video. Took it to the Apple store and they said it was either a bad video card or the screen was damaged. Within the past couple years, I have replaced the screen, the hard drive, the ram, and the battery - all to prolong the life of my powerbook. I've opened it up and checked the logic board to look for a pinched cable or any sort of damage and nothing. I've taken off the bezel and checked for the same and nothing. Apple says they do not supply parts for computers that are older than 5 years so I'm kind of screwed there. Does anyone have any suggestions? Thanks
PowerBook, iOS 4.2.7, PowerPC
