Not sure what you want here, there is no setup, if it malfunctions you have damaged parts in the changer.

Remove the short that is causing the protection to engage, then power cycle, assuming it's a short circuit protection. If it's going in to thermal protection, then shut the receiver off and let it cool. If all speaker wires are disconnected and the unit is cool to the touch but still appears to be in protection mode, likely one of the output transistors has failed an will need to be diagnosed and replaced. Don't neglect to check the ESR of the electrolytic capacitors if you find a failed device internally.

I have seen several things that can cause this. One is a capacitor that holds the memory in the cpu. Another is a voltage regulator and then there are failures in the final amplifier transistors

Unplug all your speakers and components. Then turn on, if it still locks up you have one of maybe 5 safety features hooked up that are built in to stop your amp from blowing. You will need to replace board or have some cool tech dude desolder and isolate . Look for wiring diagram for safety shut down system. Sorry but if it doesn't do it after you disconnect every thing then check each speaker with ohm meter to read factory specs.

It's in protection mode. Disconnect all speakers and hold the Tone and Straight buttons while hitting the power button. Hold all buttons down for 3 to 5 seconds. This will turn off protection mode. Now power down then back on. If you haven't damaged anything it should work fine. Make sure all speaker connections are good. Always power down the unit before making any speaker or other connections.
