iMac A-1311 820-3126-A Wont turn on


Hello guys,

I have one iMac A-1311 and it won't turn on. In the board, the LED's won't turn on either. I change the A/C power supply and don't solve the problem.

if theres no led then sounds like theres a board level component shorted in which you would need to test or could be a dry solder joint. check caps for bad solder joints.

Did you open it up and check that the connections to the power supply socket are fine, it could be the on/off switch also
