Does the TV work on shore power but not on the generator? I have never heard that one. If that is the case, it must be that somehow all the electrical outlets are not fed by the generator. Inverters are often hooked up that way, but generators are usually not. You can easily check that by checking the power at the outlet that feeds the TV. If no power is going to that outlet while under generator power, you need to call Thor and ask if that is normal (I bet it is not) and get a 110v electrical diagram for your coach. Sounds like something is miswired.
