Hello everyone I have a 1.5 Ghz 12" powerbook G4, which was working fine until about 30 minutes ago, when the screen stated to go black-I had restarted the computer numerous times, and the screen went out about 1-2 minutes every time I got on. Then it just went black, and stayed that way. I can hear the computer whirring away as normal, the only problem is that the screen is AWOL. The volume works, and I can even get it to shut down normally by pressing the power button and pressing enter. Any suggestions? This just started seemingly randomly, and I need my computer back! Edit: I've already tried zapping the PRAM and holding down "R" While it was booting up.
