The thin walls do not do well supporting the TV sets. The screws just simply pull through the 1/4-wall wall boards...
You have to use a back board that is fastened to the corners framing and then install the TV mount using regular wood type screws...
This is google view from a regular wall showing a typical back board installed.
I was always thinking the only thing that revolved was just the TV set that mounted inside a framed box...
