get to the air mode or is there? i bought a camper and the guy that owned it previously was getting 24 clear stations from an antenna with a booster and when he left he unplugged the tv and took it and i moved in and plugged my audiovox tv in; and i get nothing no picture no sound and my dvr doesnt do anything either and i know an antenna is not needed for dvr because it has wires that go to tv and no antenna wire so what is my problem i also tried another tv with the same results other people tell me i have to get into the airmode but there is no switch on set or there is nothing on main menu to get in airmode it has tv/cable i put it on tv because i dont have cable can anyone out ther tell me how i fix this problem we checked wires antenna connections booster and we get nothing but white with black srambly screen the owner before us had 24 real clear channels
