Assuming it's mounted exactly like an ACE TV in the same position, look for 2 black straps tucked up at the bottom. Pulling these releases the lower latches which allow you to pivot the bottom of the TV out and lift it off the top hooks.
or if its anything like my 2014 Axis the bottom trim piece is held on with the same thing as the drawer latches that keep the drawers closed while going down the road. A gentle tug on the bottom trim piece is all that is needed to pop it off. Once off you can see the two latches that need to be flipped to release the TV.
