Have you had a power outage or have there been thunderstorms recently? If so there may have been a power surge that has affected your receiver.

If you can interpret circuit schematics, have the appropriate equipment and are aware of working with dangerous voltages then the service manual for your receiver (see link) will be of some help to you in solving the problem.

It may be that a fuse has blown in the power supply, BUT there is always a reason for this. It may also be that a power regulator has failed etc. The cause of no power will have to be proven by diagnosing the problem using the correct equipment and fault finding techniques.

If you do not know what you are doing, it is extremely dangerous to remove the cover and check inside the unit. There are lethal voltages present. It is better to take it to a reputable, professional electronics repair centre and ask for a repair quote.
