Tim, the most common problem is that when they installed the coax cables they did not tighten the connectors enough. You will need to locate the splitter that has the two Tv's on it and with a wrench just give them a little more tightening. Just enough so that you can not loosen them by hand. They need to have a solid connection or you will not have a good signal/picture. I would assume that the splitter is in the media center. I had to remove the Tv antenna amp cover plate to get at the splitter.
Our bunk area Tv does not get a perfect picture when on the antenna, but when it is connected to cable it is perfect.
