I got a new rv that has a Furrion tv. I have Dish network with a Dish Hd satellite dish. I'm able to receive over the air channels but get no signal from my satellite. I have turned the power booster off and have it connected with a HDMI cable and still no signal. We used the satellite with our old rv the morning we got the new one and it was fine. Could it need recharged only being off for a few hours?? I'm totally at a loss. It just shows no signal. HELP please!
