标题:

Only diagnostic led 2&3 lit

文本:

I have a mid-2007 iMac 24" 2.4 Ghz. When I got it, it did not start up. The fans would spin up and then stop. The screen doesn't even flicker. I saw that the diagnostic leds 1,2 and 3 would light up, but not the forth. So I replaced the video card and nothing changed. Next I replaced the logicboard, which then gave me a different set of leds. This time only 2 and 3 were lit. #1 and 4 never come on.

Assuming that the video card and logicboards I purchased were good, my only other option, would be the power supply or should I return these things to the store and scrap this POS?

iMac Intel 24" EMC 2134 and 2211
