Hello everyone, new to the forums and just need a few pointers. I have a 20" imac A1076 power PC, and a couple years ago I came home from a weekend away and my iMac was off and unresponsive. I brought it to a local computer repair shop and they told me the power supply was bad. After parts and labor they wanted close to $700 to do the work. I said no and purchased a laptop and stowed my iMac in my closet until a few days ago.
I opened up the case to remove the power supply still under the impression that was the issue. I followed a troubleshooting guide on apple support and its leading me to the logic board being the problem. The article was archived so I don't know how relevant it is, so please correct me if I'm wrong.
Power button on back panel does not start machine
The diagnostic LED 1 is illuminated indicating power supply is live
Internal power button does not start machine
Reset SMU, tried internal power button again, machine does not start
Pressed internal power button again, LED 2 does not illuminate at all indicating logic board needs to be replaced.
Bellow is the link to the guide I used, if anyone can take a quick look and let me know if I'm correct in my diagnosis I would really appreciate it. Thank you
