We have a 2018 3011 DS and a Furrion TV. It was working fine until this trip. Now our Over the Air function will not work. The power boost button is on, I have checked all connections and they are tight and the in line fuse looks fine. Not sure why we cannot get over the air reception. Even checked the roof antenna and all looks well up there. We can't get to the wiring as it is all concealed. Any thoughts?
