just take the PRAM batt out and leave it unplugged over night. one of my dads MDDs acted the same way as yours and not even a CUDA reset did the job. the battery trick finally did put it back to live.

I've just taken my PMU battery out, waiting till tomorrow to see if it helps...

This has just happened to me too on a G4 'digital audio', except that after a PMU reset (which I did very carefully by the book) I've noticed a clicking noise from the power supply whenever the power is plugged in.

But there is still absolutely no other sign of life, not even the power button light coming on while I press it. Moreover, the monitor completely died, in a similarly absolute way, at exactly same time! That seems to be the oddest thing about it. The fuses for the cpu and monitor are both fine.

I can't say exactly what was happening when it happened because i was out at the time and my 11 year old daughter was using the machine. She reported that the power light on the front was flashing, although it wasn't by the time I saw it.

So, although I'm hoping for a result from Bolle's battery trick, I'm kinda guessing it's not going to work... does anyone have any idea what the next step is? Short of hiring someone to fix it? A new power supply, for instance?
