You literally have the exact same problem as I'm having with my 24-inch iMac! I'm taking it to the Apple Store today to have them diagnose it. I'm fairly certain that it could be the power supply. I doubt it's the logic board because nothing's ever happened to it. . . . Power supplies are known to suddenly die. Logic boards-- not so sure about that.

I just got back from the Apple Store. They said it could be anything shorting out the power. Like a bad disc drive, the hard drive, anything that could be pulling too much power. It could also be the power supply or the logic board. These things are pretty obvious, but I'm going to go ahead and order a new power supply for my 24-inch iMac and see if it fixes the problem. I've isolated every other part and that's doing nothing. :|

Let me know if power supply will resolve this issue. Where do you buy parts for your Mac? Thanks.

Hmmm... Hearing about the LEDs means that your iMac should be working properly. Have you tried resetting the PRAM?
