    I had the same problem several years ago with 22" ACD. Apple store tested my G4 tower - no luck. Finally, they checked the display itself and found it at fault. Luckily, it was still under warranty and they sent it back to Apple. Apple fixed it. No problem since.

    I have a Dual 2.5 PPC Powermac. I just installed Leopard on a separate internal drive and am having trouble getting it to sleep properly. Originally, the screen would go black and then everything would mount right back up after a couple seconds. I read that deleting any HP folder in your system/lib/frameworks would help...now my external drive unmounts and the screen turns off, however my computer doesn't go into deep sleep mode (pulsating light, drives off)--anyone know what the problem could be?



    Thanks
