I am trying to connect my Samsung 56" DLP HDTV to my JVC THD50 home theatre system, all the speakers are hooked up correctly but I can't source from the tv to the speakers correctly, I connected a digital optical audio cable from tv to receiver

On the rear of the receiver you will notice several AUDIO IN connections. Make sure that the AUDIO IN and the receiver's input selector match (for example, if you are connected to AUDIO IN for the VCR section, the input selector on the FRONT of the receiver should also be VCR). Also, make sure that the input selector you are using is set to "Digital Audio" or a digital audio enabled equivalent and NOT analog. Check all connections again to make sure you have not grounded any speaker wire. Check to see if "MUTE" is on TV or Receiver. Try another audio in source just to make sure the speakers are connected properly. If that works, you can pretty much decide that it's either the input selection is wrong or the audio source is not set to digital 9also check to see if PCM is enabled and try setting to "AUTO" if you have that function. If you have option on receiver for speakers A and B, make sure selection matches your wiring.
