At our FL campground we are supplied a box and remote to use their cable. YOu have to disconnect the cable from your TV, connect it to the box then connect an additional short cable back to the TV. It also requires a transformer. Some places don't do that. Also, the very first time we tried to use cable the tech had left the TV set for over the air because we tested that in the lot. It took me a very long time, and a call to the manufacturer of the TV (in the paperwork) to get the right settings in the TV. They absolutely made no intuitive sense. I wrote them down but now sort of have it remembered and can get it going with trial and error (we watch virtually no cable tv). So work on those settings; I'd bet that's where your problem is.
