need a back up monitor

This thread just saved me aggravation and money. I followed the advice above and emailed RVCAMS and asked about a replacement. Within an hour got a reply back from Tim giving me some trouble shooting advice before buying. I followed his steps (3 detailed emails from him) and voila, my monitor works perfect. To me it says something about a company that will help a person that has not been a customer even if it nullifies a sale. When I do need a monitor, I'll call Tim.

Thanks to the OP and others who contributed.
