Feel like a nimrod for this, we have parked for good and we are actually using our tv. Well trying to use it anyway, I have a 315RLTS TT and the place we are at has a box for cable tv. I have tried every configuration in the pass-through where the connections are. I have tried youtube and everything I can think of (which at 70 isn't much), including my older son the computer tec. Any help at this point will help. I need help getting the signal into the bedroom and the front room.
