Not Turning On Suspect Faulty Power Supply
I have a Mid 2011 Imac 21.5 inch 2.7ghz Corei5 EMC: 2428 that won't turn on and I suspect it is a bad power supply.
No lights on the logic board.
Please tell me how I can test to see if it is actually the power supply and not the power chips on the logic board or something else that may be the culprit before I purchase a new power supply from ifixit?
Thank you in advance.
