iMac 24" 2.8 EMC 2211 doesn't power on

Hey guys,

A year ago I bought a second hand iMac 24 inch, 2.8 320 GB SD iMac. Worked fine for a year. Last couple of days it was in sleeping mode. Today it doen’t boot anymore.

No fan, no sound.

When pressing the power button there is no fan speed. I red all the topics on here, and some on google, and this is what I tried already:

Switching multiple power cords and outlets.

Pressing the button for 1-2 minutes.

Removing RAM

So I decided to open her up to look if the indicator leds give any more info. They are all off.

First thing I was thinking about is try to change the power supply, but I found out that is about 150/190 dollar. Half the price of what I payed for the whole Mac.

Anything I can try ?

Update (09/05/2019)

Ordered a new power supply and it works again :)

How do i find out if the capacitors are safe to handle after unplugging ?


Leave the system off for the night and with the AC cord disconnected press and hold the power button for a good few minutes.


Thanks ! And by the wiki page you send i pressume i look for visual damage on the capacitors like rust, burst and leaks ?


Take a good read it will make it clear what caused the issue and yes any visible damage to the caps or leakage is the sign you need to replace them.

Hi Patrick !

In view of the tests you have already done, it is indeed very likely that it is the power supply.

Maybe you can get a second-hand or collect it on an iMac for spare parts.
