Hi rvowner,
Welcome to the Heartland Owners Forum. We have a great bunch of folks here with lots of information and all willing to share their knowledge when needed.
You don't give us any information as to what unit you have. Trailer, type of dvd, or tv. The black and white could be caused by several different things from settings on your tv,, to bad connections to wrong connections.
Help us out and the Heartland family will have some answers.
Enjoy the forum.
