    Any chime? Otherwise suggest power supply or logic board failure. If so not worth repairing alas.
    Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    No chime but the light comes on. Could that be a power supply failure.

    As Harry stated, either the power supply has failed or the logic board is dead. Check the power supply first. If you have a VOM go to iFixit: The free repair manual and look at the breakdown for your iMac. That should show the PS and from there you can use your VOM to check voltages.

    Power supply comes in at $140 and here is a 'how to'. iMacs are not very easy to work with.

    Installing iMac Intel 20" EMC 2133 and 2210 Power Supply - iFixit
    Using OS X.7 or later make a bootable USB thumb drive before running Installer!
