Do you have 2 jacks in the back? If so try them both one is for cable and the other satellite.
Make sure the booster is of by the main TV.
Take of the jack with the booster and make sure all the connections are tight.
thanks it has two and also 1 that says b&b did not turn the booster on will try that tomorrow thanks for the tip
If you have not fixed it, you have separate cable/TV and Sat connectors at the convenience center. The top is Sat the bottom is for cable. The booster is only used when on antenna. inside at your ent center, the SAT connector is the one not connected to the booster/12v plug.
