It appears that the bedroom TV mounting in the 364TS is similar to the 378. Since we don't have a need for a TV in the bedroom, I converted it to much-needed shelf space. As already stated, access to the mounting screws is from behind through the small panel in the adjacent closet. Much to my surprise, there was a standard 110v electrical outlet (pictured), which I've turned into a charging station for batteries, iPhones, etc. I used the monitor mounting panel as the bottom of the cabinet, framed in the space with 1x2s and used Minwax stain English Chestnut 233 on some 3/16" oak plywood from Lowes, which I used to make up the side and back panels.
