Jessbell79, I am not too sure about your trailer but can give some experience information. I have a Big Horn 3875. The TV in the slide out in living room. Above the TV is where the cable or the plate is located where the coax hooks to tv via coax or HDMI cable. If yours is any similar try this, its free, go outside and if you have a slide out there, look for where the cable comes out of hole under the frame and may be in wrapping together with other wires. Try to find and the the coax runs to slide out and up the outside wall to where your TV is. If you do this, then trace the coax into hole in frame that goes to underbelly. Follow it and 1. Could be loose connection to barrel connector, or could even be not connected at all since no signal. 2. Then if you can not find you can undo the bottom cover or corplast or whatever its called and try to find the coax and reconnect and tape together. This has worked several times. Think about this, the trailers are put together in separate pieces, when they put the slide in the trailer the coax is already ran to the TV, so the coax has to be hooked up someplace. As mentioned about the spliter before, I have a different opinion if you are not using the outlet underneath. I say do away with it and put a barrel connector instead. Hope this helps. Any further info needed please contact me if I can help. Regards, Dave
