Audiovox van TV

bought an old conversion van and the previous owner never messed with the TV, which is original to the van. I hooked it up to a dvd player and found a remote on ebay. Amazingly it works, even gets the TV audio to the back speakers. Can anyone tell me why the picture is just a strip across the screen? It is like this in DVD and static (tv?) mode. I tried using the menu and picture select buttons on the remote to open up some options, but either nothing comes on screen or I just can’t see that part of the screen.

Any hope for this dinosaur?

Included pictures of the “strip” in both DVD and TV mode and pictures of the remote and back of tv.
