Well, I have nothing here left with the middle TV to get a picture of.
I did confirm mounting.
1. on either side of the TV there is a black fabric speaker cover.
2. The TV is mounted to an aluminum frame.
3. When you pull the speaker covers, you will see the screws that mount the aluminum frame to the cabinet.
4. Once those are all pulled, you can slide the whole TV and frame on way to get the end of the frame out.
So in theory, you could pull the TV & frame, mount some plywood to that aluminum frame and put whatever TV bracket you wanted onto the plywood.
