I have just been given a Denon AVR-1708 A/V receiver without the remote. I am behind the times, and I like the stereo stuff out of the sixties and seventies, and the new stuff is great but more complicated. The AVR- plays great on FM and AM and sounds great but when I use a DVD and TV, I get a picture but no sound to the speakers. I have tried various input and output configurations, and nothing works. I am sure that either I am not programming the unit correctly or the unit is bad. I can use another A/V unit and it works fine. I am sure that when playing a DVD, I am not sending sound to the speakers correctly. Any suggestions of fixing an annoying problem. Thank you.
