I'm having a problem with a friends old rev A bondi iMac and I was hoping someone here might have experienced this one before...
When I press the power key I get the normal startup chime, can hear the fan and hard drive kick in, but then the whole thing powers itself off within a few seconds, even before anything appears on screen. The power button lights up yellow-orange at first, after the startup chime, then goes green for just a second before the whole thing shuts down. No error beeps at all. If I press the power button again, nothing happens. I have to disconnect the power cord for few minutes, then reconnect it, in order to get it to do the same thing again. I've got the service manual (PDF) for it, and have read thru some of the power-related troubleshooting sections, but I've never really taken on an iMac before, much less used a volt meter to test components (though it doesn't look to difficult), but I don't own one anyway. I'm not afraid of taking any Mac apart, it's just that this is my first iMac take-apart, and I know there are certain precautions that need to be taken if I get in near the CRT, but I'm hoping I won't have to get in that far. I've opened it and taken out the logic board/mass storage chassis, and have tried just about everything that I think I can do there. Things I've done so far that haven't help at all: - swapped out the power cord, keyboard and mouse - reset the PRAM with command-option-P-R - remover PRAM battery for 10 minutes (actually overnight) - replaced the PRAM battery - pressed Cuda button - removed add'l RAM 128mb module - removed and reseated processor - removed both the HD and CD drive Help!
