Just bought a 2012 Bighorn 3185. Second day out on our first trip and the living room tv won't work. Had the red light and hit power button and the red light went off and nothing else happened. It seems to have no power. Have checked the plug in the back and changed outlets. Nothing worked. So now we are watching a 19" (not quite the same). Any ideas? I am on a 2 month vacation. Thanks for any help. MH new to the Bighorn family.
