No power and will not make any sound
I have a iMac Intel 21.5" EMC 2889 that will not power. When it is plugged in there is no sound or anything that would let you know its starting. what I have done so far is as follows. I checked the power button and it makes contact. I also checked the resistance of the input plug to the internal connection with a ohm meter. I have continuity on both wires. I also replaced the power supply with a new one. I even disconnected the hard drive and it still will not make a sound. So I am down two two items I think. The display and the logic board. I am thinking logic. Is this a common item to go out?Has anyone had this issue? If so how did you resolve it. I don't want to buy any more parts unless I know for sure.
Thanks for the quick replies. I didn't know they still had the LEDs. I went back to it and plugged it in to see if I had any LED lights on. They were slightly lower on this model but I found them, in case anyone has this issue and don't see them look a little lower than the location on the photo. Anyway I plugged it in and as soon as I did the first LED came on but then went off quickly. I then unplugged it and replugged it in. the second time the LED did not show at all to be on. So after its initial plug in the LED will not come on. I will leave it unplugged and try again. But I only saw one LED come on and it went off quickly. I suspect the logic is bad as well. Would this be a good deduction?
