Ok, the first thing I would recommend is that you remove the rear cover and inspect the power supply carefully for capacitors that have buldged out at the top, The ones located on the top right side of power supply are ussually the culprits, They can be easily identified as defective by expanded tops.

Are you able to check voltages on the power supply to see if the voltages are correct that go from the power supply to the main board
There should be a connector from the power that goes to the main board, the voltages should be marked either at the power supply end or the main board end, there should be a 5 volt stnby along with maybe a 12 voly line
If you have the standby voltage and the unit does not power the relay on when the power button is pressed most like your main board is defective.
