I am sure there are more than one type of mount on these rigs. On my Axis, the outside TV was bolted to two vertical brackets and it was easiest to unscrew the brackets. The inside TVs mount clip onto a permanently mounted bracket and you can reach up from the bottom, about a third of the way in from each side and feel a small lever, then pull the lever toward you and lift the TV off the bracket. I am sure there are other types.
