The most common failure of a class-AB audio amplifier is a shorted output transistor. You can Locate the protection relay (if there is one), and measure the voltage "before" it, with no input. If there is DC voltage, one of the output transistors is probably shorted.

When it comes to power if it is not working, there is not much to be done for troubleshooting. Turn off, wait, then turn on. Fix? Check manual for indicators. Check fuses and cables/ cords. There is no point in opening the unit. You will most likely shock yourself. Don't.
