HOW DO I RESET THE PROTECTOR MESSAGE OR IS SOMETHING WRONG WITH THE RECEIVER,NOTHING IS CONNECTED AND THE PROTECTOR MESSAGE STILL COMES UP

I have a SRT-D1011 manual, but I think I have the wrong Manual. I think I should have the STR-D1011S. Do you know what the "Control S" on the back of the unit does? Thanks

hi I have had that problem 3 times in the 15 years i have had that receiver. a small component on the board that lead out to the speakers. it usually happens with a power surge. i have sent it to be repaired. usually 50 bucks. I am looking for the reset sequence to the receiver if you know anything about that. good luck with it. Cheers Christian
