With your sources connected disconnect the speakers wires from the back of the receiver. Does it still shut down when you change inputs?
If not then the receiver was going into protection because of a bad speaker or speaker wire. Reconnect them one at a time until the problem returns. That will identify which wire or speaker is bad.
If it happens without any speakers connected then disconnect the sources and reconnect them one at a time until the problem returns.
You can also try plugging the receiver into a different AC outlet with an extension cord.
