I have a iMac A1418 (emc 2833) that is not turning on
The Diagnostic LED #1 Blinks when the Power Cord is plugged in and if I press the Power Button it Blinks faster.
No other LEDS are on or turn on if I press the Power Button
I am thinking it may be the Power Supply but not sure. Anyone have info on testing the Power Supply?
Ist dies eine gute Frage?

Here’s how to replace the power supply:
Before doing so, pull the supply and examine the capacitors (cans) on the backside. Look for swelling and or leakage. This machine is rather new to have a failing power supply but. that’s what the diagnostic LED is telling you.

Hi
Thanks for the info
I already have taken out the Power Supply and all Caps look good
So do you or anyone have some info on testing the Output of the Power Supply like you would do on a PC ATX Power Supply?
