TV Source Input Problem - 2014 Dutch Star

[TrailerFool]

I have a strange TV related problem that just spontaneously occurred in my 2014 Newmar Dutch Star 4018 model. On all of the various TVs in the coach the “Input” option for the coax “TV” OTA Antenna/Cable TV disappeared and is no longer available. I have reset each of the TV’s “TV” input to “Always” (available) and re-auto-programmed for available channels but all the TVs find zero channels available and when I go back to “Input” (on the remote) after doing the channel re-auto-program “TV” is again unavailable (greyed-out & unselectable as an “Input”). What could be causing this problem? Both the OTA antenna input and Cable TV input to the TVs had been working just fine until a day ago!

Try the little switch on the box for the satellite antenna. Besides a little button you push on and off it has a 12v receptacle for plugging in a charger plug like a cigarette lighter. I am set up for satellite but do not have the service or boxes. I do know that if that push button is in the wrong position (on I think) my tv is a blue screen. Hope this helps.
