3rd time out with 2015 Reflection...get all hooked up at the campground...go to turn the TV on to find the cable channels...nothing. Took TV off the wall to ensure outlet was ok...and it was fine. Unit is dead...has anyone else had this issue? What is the best way to resolve? Heading out to buy another TV right now that we will eventually mount in the bunk house or bedroom...just to get thru the rainy weekend.
