No power on iMac
I have an iMac emc 2428 that is not powering up. The unit was left in sleep mode overnight and the next day it wouldn't power up. When the power button is pressed nothing happens, no noises or fan spin.
I've tried multiple known working power cords and different AC outlets. I've reset SMC and tried leaving it unplugged overnight and tried the next day, still no signs of power.
Apparently there are diagnostic LEDs that I am trying to locate. I removed the RAM and looked through the bottom vents and RAM slots but couldn't see any LEDs.
My guess is the power supply is dead, therefor no LED. Or the issue is I'm not looking in right spot. I have purchased suction cups but haven't opened the iMac until I know it's necessary.
Any help would be greatly appreciated!
