iMac not powering up. USB port powers led light.
Hi,
I have a 27” 5k iMac (late 2014, i7 4.0, 295x 4gb). Tonight, the unit froze so, I rebooted it. After I power cycled it, the power would click off after only a few seconds. I did this cycle a few times. Sometimes if I let is sit unplugged for a while, after reconnecting power, I could get it to progress to booting up into macOS. But is locks up shortly after that. When plugged in, the usb is outputting power ( I have led light that I use, powered from the iMac ). I am guessing it’s either a bad power supply or logic board.
Any advice?
Is dit een goede vraag?

@gtesserac post a couple of good pictures of your logic board as well as your power supply. That way we can see what you see and maybe even find things for you to check Voeg afbeeldingen toe aan een bestaande vraag
