Living room TV, above door, on our Axis hangs on its mount. With a flashlight, look up behind TV. On our's, there are 2 levers, each of which is maybe an inch wide. Move these levers and they should unlock the TV, which will tilt outward a bit. Then lift the TV off the hooks it hangs on. On our's, a couple of the connecting cables are short and its easier to have a 2nd person there to disconnect the shorter cables, so you can completely remove the TV. Also, on our's the TV's power plug plugs in to a recepticle behind the overhead kitchen cabinet nearest the door.
Our other 2 TV's, the ones in the bedroom and outdoor, are held in place with magnets. Gently pull on the bottom of the TV and if your's is like our's, TV will swing out and away from the wall.
