Recently purchases a 2018 Jayco 29BHDB. Daughter decided to put a DVD in even though there was one already in DVD player. DVD was taken out but now DVD player acts as though there is a DVD inserted and sometimes won't even register the "DVD" input on the IRV panel. I attempt to insert a DVD and again, it acts as though a DVD is already inserted and won't let me load a DVD. We attempted "Factory Setup" according to manual but it didn't do jack. Any help is appreciated.
