Hi Tom (& list)
This is perhaps a shot in the dark, but on macs fro the LC series to G3s. I've cured seemingly dead/inexplicable display problems simply by replacing the mobo battery.
If yours is more than a couple of years old, it's certainly worth a try, otherwise it sounds like hardware (even as simple as a dry joint somewhere) and needs a real techie to investigate. CRTs retain lethal voltage for a surprisingly long time even after complete disconnection.
All the best

My wife's imac began acting up today. We thought it was going to sleep and not waking up, but I turned off sleep functions and the video still randomly shuts down. It might go 15 minutes, it might go 6 hours. The computer is still on but the screen goes black. I can tell the computer is still on because when I use the keyboard to put the volume up or down, I can hear it beeping as it cycles through the volume settings.
Any ideas what is causing this? If you unplug it, you can always start back up again with good video.
