Answer to: Unable to turn on. Shutdown completely.I'm buying a 2007 Intel Core 2 Duo iMac 20" from eBay and it has SAME problem. The seller reports that after 5 times on/off, the unit won't power up at all. I've looked at iFixIt's repair instructions for power supply and for a newbie, it seems pretty steep on the learning curve. My question here is: If it isn't the power supply, what could it be? I'm trying to pay no more than the computer is worth including repair. New power supply is about $100-140. Are there any diagnostics (like the lights mentioned above) that can be done before I go and buy a power supply? Apple repair is $90/hour. Thanks for any help in this hour of need!
