I have a 2009 senator with the TV on a swivel panel, the power feed is through the ceiling and is 12 volt.

after 15 mins of watching the digital picture starts to break up, I believe this to be the unreliable 12 volt supply, apart from using on the mains has anyone got any advice, we use the van a lot on battery as not always on hook up sites
