Why won't my iMac turn on?

Testo:

My 24" Intel iMac (A1225) won't turn on.

When I plug the iMac in, the left diagnostic LED (#1) on the logic board lights.

When I press the power button, LEDs 2 & 3 light, the optical drive makes a clicking sound, and that's it.

The fans do not spin, the hard drive does not spin, the Mac startup sound is not heard, the display does not light up.

I've tried the following with no change:

-Resetting the SMC

-Attaching an external monitor

-Reseating the RAM

-Replacing the RAM with other known good RAM

-Booting with video card removed

-Sent the logic board and video card to Powerbook Medic for repair, they said they did a reflow of the logic board pins at the video card interface, and the video chip on the video card was re-balled and reflowed.

-Powerbook Medic also claimed the power supply was fine, but I don't know that they actually tested it.

None of these things have made any difference and I'm running out of ideas.

Any suggestions?
