Chosen Solution
When I first got this Mac there were no LEDs on when plugged in. I switched out the power supply to get the 1st LED to turn on. However, the Mac still wouldn’t turn on. I could hold the power button and plug in the power cord to get the fans running but that was it. I then switched out the logic board thinking maybe that was the issue. But nothing happens, still the same as before with the fans. Anyone have this problem before?
Update: I switched out the GPU and it turns on just fine now.
