On my ACE I have three different brackets, each holds the TV different. The main TV the bracket has two release levers one on each side of the bracket. That releases the Bottom of the TV so you can lift it up and off of the wall bracket. That leave you with the other part of the bracket attached by four screws to the tv. I just replaced that with a bracket that only holds the tv with a small set screw balance is held on a hook type system.
