I'm finally getting time to start setting up the entertainment electronics in my new 2020 Flying Cloud, starting with the TV (only coincidently in time for the Packers/Cowboys game, by the way). In short: a very nice screen of black and white static, which I haven't seen since "It's 10 PM, do you know where your children are?"
I am theoretically using the antennae. I ran through the autoprogram to find all channels. Of course it didn't find any in CATV etc, but there should be a half dozen on the regular TV. It found none. (I should say that I'm on shore power.)
My first guess is that it's the antennae. I'm working on the TV in the salon, which doesn't come out from the wall. But it looks like everything is connected properly. Another clue is the FM radio is staticky. Is there a way to check the antennae?
