Here is the thing. Please look at most other's Signature blocks here and you will see lots of information about the RV equipment the member's are using.
This is not in order to brag (although I do tend to drool at some) but to help other members help them.
A post like yours provides almost nothing to go on to help you out. Camper maker, model, year, Television make model (digital or analog), pictures of your connections; all would be useful.
Get back to us as we want to help.
