    I have a vintage Imac G5 - 17" - 1.6mz - 512mb

    I powered down today and now its not starting up. I get nothing, completely dead.

    I am getting 1 green LED light inside and I tried to reset the SMU and hit the internal power with no other LEDs on and no power. My capacitors look good, nothing broken, bulging or corroded. I had the power supply replaced a couple years ago under apple care. I am hoping my logic board isn't shot now. Can it be the power supply again, even with the #1 LED light on?

    Does anyone have any advice as to what my next step should be in trouble shooting? Even though I am due for a new computer, I just can't let it go yet.

    Thanks in advance for any help out there. It will be much appreciated.

    It could be a PSU (power supply unit) fault. If you really want to get it working again your best bet might be ebay to see if there is the same mac for sale for spare parts.
