2012 Tiffin 36LA surround sound
One day my surround system worked, the next it doesn't. Nothing changed. Have a Panasonic unit in the deck behind the bedroom TV. Using the Panasonic remote I turn on this unit, set it to D-in and I control surround volume by aiming at any IR sensor in the coach. This just stopped working. The only place I can change volume is by pointing directly at the Panasonic box.
Aiming at the IR sensors on the TVs in the main cabin makes them pulse rapidly but does not change volume. The IR controller appears fine and is lit/active.
Any ideas as to what happened?
