iMac G5 17" model A1058 dead
This mac simply stopped dead, no previous symptoms whatsoever. Diagnostic LEDs indicated faulty logic board (#1 lit, #2/#3/#4 off). Replaced logic board with refurbished one, but with no effect (LEDs same as previously). So my question is - could the problem be the power supply? In others words, could LED#1 light even if there was insufficient power getting to the logic board? If this is the case, would it be worthwhile purchasing a used working power supply? (the refurb logic board wasn't too expensive, but I'm reluctant to spend much more on an old computer if there was no certainty I could get it working)
Update
yes, I did enable the PSU with the jumper pins as indicated in the article you mention.

After you replaced the logic board, what does it do on start-up? What LEDs light up?

It doesn't start up - no fans, no hard drive spin... nothing. And only LED#1 lights up - the same as it did before I installed the new (refurb) LB.
