DVD shows no input

[JeffnBeth]

Pulled into park today and hooked up cable. All the TV were setup and all get good reception. We decided to watch a dvd (worked fine last trip). Pushed dvd button and shows no signal. DVD is playing and caught a glimpse of it on bedroom TV. Main tv simply shows no input. I have the QS53DVD control center and it all worked fine last trip . .. I'm frustrated beyond belief right now. .. anyone have suggestion as to what to look at?

Thanks in advance

Ok... so I took a step back and thoight about it.. only change was this park's cable. I switched my tv from cable to air... DVD shows up as expected. Maybe the scan of stations here is different. They do broadcast on channel 3 and 4...
