Why won't my iMac power on?
Posted on 2009-12-28
I have a 20" iMac (2006) that won't boot up. There's a little bit of history to it, when I replaced the internal power assembly after it was dead in the water after being recovered from a pawn shop post office break-in. This fixed the issue for nearly a year. Two months ago, it wouldn't start. Plugged in, the power button did nothing. I unplugged it, put it in the corner, and forgot about it until two weeks ago.
I plugged it in to mess with it, and it powered on fine. Ran it for two weeks with no issues. I came back from Xmas break to find it off. Again, the power button won't do anything. I've tried different plugs, different power cables, etc. No dice. I'm reluctant to replace the internal power assembly (it cost $300+) to fix the issue again, but I'd like to know what the issue could be, and how I can better diagnose it.
Any ideas or suggestions will be greatly appreciated.
