Not sure how you have hooked up your TV into your surround system. If your surround sys is using a DVD player for watching movies or such you may need a RFC control from RADIO Shack. I installed a DVD,FM.CD surround system and used this control to auto switch surround sys video to operate TV and use only the surround sys 5.1 spk system. The control cost about $15 and you wire your TV cable thru it, if your not playing a DVD your TV will operate normally.
