Hi, i have a 27’’ iMac with a power supply problem (i think) When i try to power on the iMac it nevers turns on but if i move the power cable sometimes it turns. Sometimes when i dont use it and i try to turn on it power on without problems. It will be a power supply problem? Logic board poblem? What i can do to discard the problems? I did the SMC Reset and it didn’t work Thanks!

You say when you move the power cable sometimes it works, are you sure its related to the iMac and not the power cable, if possible I would try another power cable first to test it doesn’t really have to be an apple one any generic one would do for testing. let me know how you get on.
