How to be sure PSU or Main logic is dead?
iMac 21.5 A1311 Late 2011 2.5 QC 2x2GB 500GB 6750M 2.5GHz
I'd like to know how to be sure witch part of me iMac is dead.
But the experiences lived on the same observation does not lead to the same
conclusion.
My iMac does not respond, nothing happens when a press power button.
None of the diagnostic LEDs are on.
My PSU generates a little noise and i can't test pinout without the normals values.
I already try the basic operations.
I would like to be sure of my purchase, if i buy a new PSU.
Thank you.

Hi
I have exactly the same probelem that over here.
No lights on the motherboard .
PSU measure the same values over here. Only 3.6V and 12V and one at 0,06V .
I also ordered a new psu from IFIXIT that I read exactly the same values from.
Is it the motherboard is dead ?
Thanks in advanced!
