I am not sure if this is an issue with G5 systems or not, but can you see any bad looking, aka, bulging or leaking capacitors on the motherboard? If not, one last ditch effort to try is to unplug system, remove battery from board, push reset switch for around 10 seconds to make sure system is drained and then let it sit with battery out and system unplugged from power for a few hours to let everything drain, then put the battery in and plug er in and boot up and re-set all your display settings before you reboot again. If that doesnt resolve it, im all out of possible voodoo to try lol -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
