I just upgraded our bedroom TV in our ACE. Look up from the bottom and see it you can see two silver phillips head screws that you can reach with a very long screwdriver or extension. Remove those and the TV should slide up and out of the mount on the back that screwws to the plywood or in our case, a cabinet door. This is what I was working with and the screws were cranked in by a Thor gorilla. I had to use and EX-Out on one of them.
