iMac does not power up
Hello, i have a mid 2010 21.5 imac that refuses to power up. The #1 diag led is on but as soon as i press the power button the led turns off and does not come back on unless i unplug the imac from the wall. No other led light up at any point.
Do you think this is a bad PSU or logic board?
Is this a good question?
