Anyway to diagnose a logic board without buying new PSU?
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?
Is this a good question?
