I have used this amp/receiver for many years with no problems. Disconnected 2 rear surround speakers to reroute cabling. Ran without them connected with no problem.
Rearranging room today decide to reconnect rear speakers. Connected one to see which one was which and amp after switching on gave error "Protector/Check Code 11" and switched itself off. Connected other speaker and still it gave this error. Disconnected them both and tryed again, same error. Finally disconnected all speakers and amp now gives this code all the time and won't stay on.
Checked manual for this code and it states "Irregular current output to the speakers. Turn off the receiver and check the speaker connections. Then turn on the power again."
As I said tryed this and still get the code. Think I may have shorted the cable of one of the speakers to the casing or something like that.
Bought the service manual for this receiver online and checked what it had to say about the code. It states "Irregular current output to the speakers. Turn off the receiver and check the speaker connection. Then turn on the power again. Becomes this display , When short current flowed with breakage of the power MOS, or when detection resistor becomes open in connection with it."
I now have the service manual and a rudimentary electronics knowledge. Need some help to maybe check a couple of components myself.
