I just purchased a Bighorn 2017 3750FL 5th Wheel RV. It has a 55" Front TV which is awesome. My problem is that it also has a Jensen Entertainment Center. I cannot get the Jensen controlled speakers to work on the TV Sound just the TV speakers. I am getting the TV signal from a Direct TV satellite system. Don't get a signal on the antenna at my location so cant tell if that would work with it Works well with a CD or DVD but not the TV. Probably an easy answer but it escapes me. All kinds of options in the menu section but nothing for TV Sound. Owners brochure doesn't help. Have not yet asked HL for help. Dealer doesn't have a clue.
