Since it doesn't even lit the power led, chances are the internal power supply is shot.

 Simple fix if you have electronic skills.

To fix it could be not simple, becouse not all power supply (switching) have the same voltage in the secondary.
The schematic is need becouse on it you will find the right voltages, components value, waves, etc. :)

I am sure you have checked, but, do you use a fused power plug? Have you tested it?

The voltage (220V) in the primary is present, but the switching seems to be dead.
