I am going to assume you have Seiki tv's. Make sure you have antenna booster off. Depending on the type of cable service the campground has Seiki tv's don't like to work. There are many threads about this problem on the forum and a lot of owners are switching out their tv and installing another brand. Shame Thor had to put such a poor tv in our coaches! I'm in the process of changing my tvs one at a time.
