My DVD/CD player has stopped working for no apparent reason. I have done extensive troubleshooting with no results. The error message that I get is "no video signal". This is a Genesis GT2.0 media player in a 2013 Big Country 5th wheel. I am also having problems getting the functions to work ie, eject, mode change, etc. Can you tell me if I need to have the dealership change out this unit or is there a quick fix that is not in the troubleshooting manual?
