My iMac will not turn on. Is power supply out?
After a couple of power bumps to our home's system, and power was restored, all home electrical panel breakers were still in the on or untripped position. The 6 outlet power strip, my iMac was plugged into, was still on, again, untripped, but my iMac will not turn on. I have tested the power cable from the power strip to the iMac, it's OK.
My first thought is blown power supply. Second, damaged motherboard. Need info. on diagnosis procedures, repair, ect.
