I removed what had to be original. Big old box TV with like a 12” screen. In the 4000, it sits in a cut out corner. I wanted to keep the new one in the same area, so mounted it diagonally in the opening. I think it’s a 22” television. Hangs off each end by like 1/2”.
I replaced with a 27" LG (27LQ625S-PU) and fashioned some wood blocks to the tv mount on the door so the tv flush mounts on the surface of the door. Remove the door for an easier installation.
Added an outlet inside the cabinet coming off the bunk outlet.
It's a perfect fit for the door and is a good size for the bunk.
