Hi,
Hopefully someone can help me. I just acquired a powermac G4 MDD with a 22" cinema display. It's running OS9 and OS X Tiger. It has been running fine until recently when I turned it on and the power button just blinks at me. It's running but the monitor will not turn on. If I unplugg the monitor from the computer the light stops blinking. Any suggestions? Please help.

Hello,
Can you count the beeps or flashes?
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.

Power supply is a little bit weak, especially 25V output?
