I need some help on setting up amp/receiver in a new home theater configuration. I have an older Yamaha RX-v1300 with polk audio speakers and sub woofer. I had never taken them out of their boxes (long story, never set up or run). Now that I have my basement finished I want to get it all set up. I have a plasma tv, media com HD tuner, DVD and VCR. The receiver is old enough that it doesn't have HDMI, either does my mediacom tuner. So, I'm going the route of component video cables and audio cables. To cut to the chase, I hooked everything up going into the receiver and with the tv out as the monitor connections. I have the two main front speakers and center speaker with two speakers in the back, plus subwoofer. It is a 6.1 in other words I can have another back center speaker but don't. I have went through the set up where it asks about large, small ot no speakers and etc. But, I turn on the am/fm and no sound. Turn on the DVD with cd and no sound. I turn on the tv and the tv works and has sound out of the two front speakers and subwoofer. No sound out the center or back???? Just wondering what I'm doing wrong. Any information is greatly appreciated.
