Hi all, I'm looking at a 350MHz iMac for a friend. It doesn't power on when the button is pressed at all. I can hear the high voltage come up for a second, and then slowly discharge when the button is pressed. The Power LED doesn't come on, or even flash. I don't hear the CRT degauss. I do hear a mild pop from the speakers. Checking the voltages listed in the service source, I see voltage on the standby circuit, almost exactly 5 volts. I also see voltage at the C10 cap, around -1.3 volts. Does anyone have any ideas on what might be the issue? Might this be a general caps problem?
Also, is there a way to run the logic board externally to test it?
Thanks!
