Found the piece holding the TV down to be easy in and out by rotating it down behind the set, same rotation when putting it back in. Was easy to remove, now putting a 1 1/2 inch hole saw through that desk top was a challenge... HARD wood! Cutting a hole behind the set, 3 seconds, same hole in the middle shelf under the desk, 2 seconds... but that desktop... burned up the whole saw LOL. But when all done, clean install of the computer connected to the TV. Wireless mouse and keyboard stows away with the computer and battery backup power supply. Now to get my satellite to work!
