Have R965 receiver that I have owned for approx 2.5 years. As I was building my house I did not use for 1 year and now have recently put back in to use. My problem is everything was working fine for approx 1 month and now I seem to be having problems. First my Optical 2 input quit, verified by reassigning same equipment to optical 3 and now I can't seem to get my subwoofer to work. Even when I try to do an auto set up it does not detect the sub. I have the sub set to active and the power assign to room 2 with room 2 feed off. I have power to the sub. Is their anything that I'm missing or is my receiver screwed? Any help would be appreciated.
