Thanks. Here is the situation, on the wooden frame there is one screw in each corner. The wooden frame does not slip over the TV (TV too big). I have banged on the wooden frame from each side and nothing. I have tried prying the wooden frame straight out without breaking it, - won't budge.
It is obvious that the wooden frame was made for this particular TV and would not be re-usable with a new TV. I have been leaning toward bursting up the wooden frame, but am a little reluctant to do so. But I don't see any other choice.
