I have a Panasonic TCP42C2 Plasma TV and a Panasonic SAHT740 DVD Player/Theater System. I am having trouble getting the TV sound to come through the speakers in the system. Panasonic Tech Support advised me to get an optical digital output cord, connect it to an adaptor to red and white/RCA cords to the system. I followed this advice, but I still cannot get the sound to play. I put the system on "AUX" and enabled other speakers on the TV and turned off the TV's built in speakers but still nothing. Any help is appreciated. Thanks.
