Different coaches, different methods of hanging the TVs/cabinets. You probably should just pull the TV out and see what is going on. Ours has square steel tubing that's tied in to the cabinetry and supporting the weight of the TV. The wood that frames the TV is held to the cabinet with 4 screws behind 4 wooden bungs. Removing the frame will expose how the TV is attached...careful, those dino TVs are heavy. Once you get the TV out, you should be able to tell what's happening. Good luck.
We must be driving on the same bad roads.
