Finally got around to cutting the purple wire controlling the front TV power. Simple, fix. Basically a relay glued to the back of a standard outlet. I disconnected the relay from the outlet all together. I clipped the red (which becomes the purple after a splice) and the white (which is spliced into the 12v supply to the antenna switch. I then disconnected the black splice they made from the 110v side and reconnected the solid copper to the pole. This left the relay totally disconnected, capped and taped.
Now I can use that outlet for needed charging/use of multiple kid devices while traveling on inverter power...
I will say this. Jayco's wiring (assuming all RV) is horrendous. If you are having cable or antenae issues, I would check all the RG-6 connectors at the splitters, etc. All mine were loose.
