Is your tv coming on? I have a 2012 Greyhawk 31DS and had to bypass the outlet cutoff relay so the tv would still have power. i havent tried to play a dvd. there are alot of posts on how to disable the relay if the issue is the tv not turning on. If that is not the issue then maybe try using a seperate dvd player other then the in dash on.
