Imac won't turn on

[renstein]

I was using my IMAc Saturday morning.. all was fine. Turned it off, then went to turn it on tonight... NOTHING! no noise, no color, no lights! Unplugged it, held the power button for 15-20 seconds, then released, then pushed it again - nothing! What could have happened, and how can I fix this? Thanks

Try different power socket? Best to cover off the easy ones. Try a different power cord as well.

Tried the different power outlet... but not a new power cord.. We don't have another one for the Imac.
