What are you trying to do with the amp? What do you mean by "The power supply is switch DC to AC"? When an amp blows, sometimes there is no visible sign that you can see. If it goes in protection mode all by itself, then it's a safe guess that it will need servicing.

I am trying to repair it. It is in protect mode and there is no visible sings such as fusable resistors burnt or transistors blow out. I want to fix it myself because it is old. I was just asking for suggestions of what to look for I have checked every cap and resistor on the board for open or shorts I don't know what eles could be wrong. The output stage is getting about 0.41Volts DC which should be AC. I don't know what is causing this to happen.
