Ours was the same never used it untill wife bought a bargain telly.Up till then never really botherd with TV when away now I cant get her to TURN THE BLOODY THING OFF!!! fun!!!fun!!!fun!!!Check that the aerial coaxial cables are actually connected! On my MH, not only had the cables been connected to the wrong sockets on the booster box, but the aerial socket did not have the centre wire of the coax cable exposed so it would never connect to the status aerial on the roof. So much for the factory's quality control - but it did explain my inability to get a TV signal!
