I find that if I deliberately point at one TV, there isn't an issue. In my previous coach, 2014 DS, I did have an issue with the outside TV coming on inadvertently. I bought these to solve the issue. They're remote controlled outlets. You plug in a small receiver into the TV 110 volt outlet and then the TV into the receiver. The TV is now powered completely off until you turn the power back on with the provided remote.
You can buy them with one receiver or six.
