Recently we were at a campground and connected to their cable system with no problem on both TVs. Suddenly, we received the No Signal message on both and couldn't get reconnected. The campground cable system was checked at our site and was working. He also checked the cable we had connected to the post and it worked also. We were able to use the TV antenna to get local channels but not the cable. Any suggestions on what to check out? We have been using the cable with no problems until now. We have a 2014 Bounder 35K.
