Chosen Solution

I’m in possession of an Intel iMac 2210 and it appears to have a dead power supply. For a little background, it went through some sort of power surge that rendered it useless. I’ve opened it up and looked at the diagnostic LEDs on the logic board and they don’t seem to turn on at all. So either I’m looking at something totally wrong, or signs point to a faulty power supply. But here’s the thing, although I have no issue paying the $140 for a replacement power supply, I don’t want to spend that money just to find out that it was actually the logic board that crapped out on me. So I was wondering if there was some way for me to test the logic board or something to greater guarantee that the power supply was the only culprit in this. Alternatively, I was wondering if there was some way for me to connect pins from a PC to the iMac and see if it turns on that way? If not, then would you happen to know if iFixit will take back the replacement PSU in the case that the logic board is in fact dead? I read that they take back parts as long as they work and give you a percentage of the money back, but how much would that percentage be?

JanHenrik, check on here for a quick reference.

Since you have to remove the PSU anyway you could take it out and test it before purchasing a new one. If you want to talk to someone from iFixit (this is the volunteer DIY help forum) contact iFixit direct. If this Answer is helpful please remember to return and mark it Accepted.

If you look at the Psu look carefully you will probably see a burn mark somewhere. I’ve had some machines some techs thought it was Psu - they changed it - no change Said it was a logic board. So I take a look and find out the problem is not the Psu nor the logic board but the cables that go to the power supply from the connector. Sometimes you can even smell where the issue is lol
