I have a 2007 Southwind 35A and I have no TV signal. I spoke with Camping World service and they think some how the power booster may have been shut down. The problem I can not find it. There are no boxes that can be powered that have Winegard on it. I have a slecter switch with no power and a AVS 100 HD Smart Source box that has power but I have no idea what it does. Anyone know where the Winegard box might be, I've looked everywhere!
