My iMac sometimes starts and other times it won't!
I have 27" iMac 27 i7 2009 (logic board 820-2733-A)
It's working sometimes and sometimes not. But only when I unplug power cord. After few seconds I plug the cord back in to start iMac its start normally but sometimes this trick is not working.
I already replaced the power supply, but same issue. I also replaced CMOS cell. When I plug power cord the first diagnostic LED lights.
Not sure is this power supply fault or logic board I'm confused!
plz help. sry for my bad english
Is this a good question?
