A:
There is a small locking lever (2) on each side of the cleats that connect the TV to the wall portion of the mount. I might suggest 2 people and a small flash light to see the release levers more easily. One person on each side to press a release lever, then simply lift the TV 2 inches off the cleats.
If you still have trouble look it up on the web site; it has a picture of the unit to define the exact location of the levers. If that is not helpful you might go to a BEST BUY STORE and look on the back of the box. There is a photo of the unit on it.
Hope this helps you.
