Those Winegard wallplates can easily go bad and I'd do that before I started chasing phantom splitters. If the TV signal gets to the bedroom just fine but the cable doesn't then it doesn't sound like there's anything wrong with the actual wiring. If you only have 1 coax connector at the bedroom wallplate and no outside TV connection then there wouldn't be any need for an additional splitter.
I thought for a while that that (the wall plate) might be it with ours; it wasn't.
I tried a long time ago complaining to the dealer; they thought everything was just ducky (NOT)
. I tried replacing the plate, without success. The only thing left is the wiring. And considering the connections I had to re-do at the plate to outside, I won't be at all shocked if I find more sloppy work
Unfortunately, I'm at a disadvantage when working on our rig, because there's no good place to park it near our house. Both our cul-de-sac and our driveway are on a significant slope; and working on it at the trailer lot requires that the neighbor's storage spot be open so I can run the slide out. Even then, at the lot I have no cable source to feed it; only the antenna, which works just fine. Arrrgh.
