Diagnostic LED-2 stays off but HDD is running
So I just opened an iMac that doesn’t give any sign of life (black screen)
The onboard diagnostic LED-1 is on as soon as I plug in the AC power cable, I can also hear the HDD turning on when the power cable is plugged in.
I can turn the HDD on and off by pressing the power button for 3 seconds but everything else seems to be off (fans not running) also LED-2 stays off when I plug in display, so only LED-1 is on everything else is off.
Do you think the power supply is not giving enough energy for every part? Or do you think its a logic board problem?
