Echo from surround sound
I have a Toshiba 57" rear projection tv, an Onkyo 5.1 receiver. When I use surround sound, there is an echo and the sound is not in sync with the tv. Don't want to start buying new stuff because I don't know the cause of the problem... And I still have a turntable, cassette, and CD player/recorder. Oh yeah, my main speakers are Bose 401's running 4 ohms, center and rears are Bose with 8 ohms.
