You can mute the television speakers altogether. With your remote, press:
Menu > Sound > TV Speaker > Off
This will allow no sound from the television, and won't display the speaker mute icon. If you need more help, the instructions are available (with pictures) on page 38.
I have a Samsung LN40a450 lcd tv and when I turn on the receiver for my speakers, the tv makes a horrible nosie. If I turn on the mute button then you have the mute symbol in the middle of the screen during the movie. Only solution I found is to turn the volume on the TV down to 0.
any other solution?
