iMac does not power on.

History

I press the power button and the light goes on but nothing comes up on the screen. I also cannot turn it off, the light stays on till i pull the power off. Even if i hold the power button for a while.

Thanks

i found some info after i posted. No bad capacitors. 2 LEDs are on.

Open you iMac and inspect for swollen or leaking capacitors - they look like little cans with 2 feet soldered to the logic board. If you see this, you will need to replace the logic board.

Also, refer to this Apple Knowledge Base article for details on how to use the on board diagnostic LEDs:
