Hi,
As there could be a number of reasons for your problem unfortunately there is no simple answer.
It could be anywhere from a loose connection to a problem with a protection circuit etc.
The best way is to follow the No Power troubleshooting flowchart in the service manual to diagnose the problem.
Here is a link to the service manual for your receiver. Scroll to Sect.5.1 (p.28) to view the procedure.

To download the file, when the sentence below the Document Preview box changes from This file is downloadable free of charge: ...processing... to This file is downloadable free of charge: Get Manual, click on the Get Manual as this is the download link. Be patient as it takes a little while to find the file. (See images to see what I mean)

Hopefully this is of some help.
