There is a connection point in the electrical compartment that one end of the cable is connected to and the other end goes to the pedestal. In the cabinet under the tv, there is an amplifier that is used for the roof antenna. That should be off. Go into the setup menu for the tv and do a station scan for cable not a station scan for antenna. You should then be fine. Both the living room and bedroom tv's should work off the cable. I just had a situation this past weekend. I went through the setup and about half the stations were very snowy. When I asked at the office, they said that thery were not having a problem. There was no one in the site next to me so I hooked up the cable to the pedestal on the other site and the picture was crystal clear. There was some sort of problem with my cable hook up.
