I recently hooked up a Onkyo TX-NR809 that i inherited when my brother in law passed away. Without getting into too much detail I swapped it out for a denon that I intend to relocate to a different area of the house, so all speakers are in place. I connected all the speakers and sub woofer, used RCA cable to go from the TV to the TV input on the receiver - tested it and it worked fine. Then I started playing with zones and now I cant get any sound - i dont know if i caused it by messing with setup or it coincidentally stopped working. Before I disconnect and bring it in for repairs, I am looking for help with diagnosis or maybe some advice on how it is set up. The owners manual for this receiver is very long and complex. I just want to run my TV through the receiver for movies and music. Thanks in advance.
