I am using my new LG TV (model number 42LG30) with a Panasonic Home Theater (model number SC-PT760). I have been able to play a DVD, watch it on TV and hear the sound through all of the home theater speakers. Note that the only cable from the TV to the Panasonic receiver is one HDMI cable. Also note that the TV is connected to a Direct TV cable box. My problem is this: I can’t get the Panasonic Home Theater speakers to work when I watch the TV. That is, when the TV is on the sound only comes from the TV speakers. How can I listen to the TV (movies, etc) through the Panasonic speakers? PLEASE HELP. Thank you.
