Chris, You may have the same situation I have. My TV quit working so I started looking for the antenna amplifier--the power booster. My previous Southwind had an amplifier box as the others have said. Check your switch box, the one with all the buttons on it. See if it has two 12V wires going into it. It will be in the back with all the other coax cables. If you have these wires, and I would be willing to bet you do, then the antenna amplifier is built into the switch box. That is the only reason for these wires, to power the amplifier. Check for voltage at these wires. No voltage, then try tracing the wires back to a fuse somewhere. My problem was, there was voltage at the two wires so I had to replace the switch box. Seems like it was about $50. TV now works fine. (I put an in-line switch on the 12V plus wire and I turn the amplifier on and off as I need it, as I didn't like power on the amplifier if I wasn't using it). Hope this helps.
