Access stereo

The Furrion DVD Player (not sure if it's a 3100 because I'm not near my trailer) is located in my Stratus in an upper kitchen cabinet. The faceplate can be removed on mine with two "hooks". I used a scribe, angled at 90 degrees. Pull on the middle of the faceplate on each side. Before I figured out how to remove the faceplate (which is thin plastic), I opened the cabinet below and removed the "ceiling" of that cabinet. It was screwed on with screws in each corner. I was able to get to the wiring harness by exposing the bottom of the DVD player when I removed the lower cabinet's "ceiling". I reached behind the DVD player to remove the wiring harness. My DVD player wouldn't stop cycling even when it was off. I can't remember if there was a fuse on the power wire or not.
