Hello and thanks for your question. I look forward to assisting you today with the best answer possible.
Push Protect Power indicates that the protection system has been activated because of a short inside the receiver and to protect burning of the the speakers and prevent fire.
As of first step, disconnect all the speakers and other input connections from the unit and then turn on.
Tell me if you see the same protect message.

I am extremely sorry to say I've a bad news for you.
It could either be a blown power supply or a board and it needs to be replaced.Look for either a pulled wire, or check any wires coming off the transformer where they plug into the board. There could be a cold solder joint which needs to be resoldered or a faulty capacitor in the power supply, or near the protection relay.
Diagnose your self by visually inspecting the large filter capacitors for bulges, leaking at the base or the solder joints. Also, you can test the output power transistors by verifying that only one leg of them are common to ground. If more than one leg is to ground then it verifies that the transistor is shorted.
This way you will be able to know which one is at fault and then replace it accordingly.
