No Screen, LED #2 Off, No Chime
Hi so the iMac will not turn on, the screen stays black and there is no chime.
I opened the iMac and noticed that LED #1 stays on but when I press the power button to try and turn on the iMac, LED #2 never turns on.
I can hear the HDD spin up when I power on the iMac but no fans turn on. So I’m not sure if the PSU is bad or not.
I tried to power on the iMac with everything put together, without an HDD, and without RAM, LED #2 never lit up.
I ran a test on the RAM and HDD and both passed, so my question is if it is more likely to be the PSU being bad, the cable to the logic board being bad, the logic board being bad, or the CPU being bad.
Cette question est-elle utile ?
