iMac 27" power problems
I am having powe issues with my iMac. I get nothing when I hit the power button. I have installed two different power supplies thinking maybe the first one was DOA, but not the case. There are also no LED lights lit on the logic board when I have it plugged in. I thought for sure it was a PS issue but I was wrong. Any help is appreciated. I have had this computer a little over a year and didn't purchase Apple Care.
Also, prior to this all happening I was hearing buzzing noises out of the back of the screen. I have read that this is a known issue.
Es esta una buena pregunta?
