This problem might appear silly, but I cannot remove my TV from its
stand.

I have a CRT Toshiba 28" TV which I inherited, that is positioned on a
stand. This is one of these open box types with 2 shelves for including
2 other electrical boxes, dvd, vhs recorder etc. What I want to do is
simply remove the TV from the stand. However, it appears to be locked
to it on the front right hand side corner. It can be swivelled around
this point however. On the underside of this area is a small
cylindrical 'hinge' type device, with a button inside which can be
pushed in or out. I had presumed this was for locking the TV to the
stand. However, regardless of whether I push the button in or release
it, the TV still remains stubbornly stuck by this one corner to the
stand. I don't want to use excess force for fear of damaging both the
stand and underside of the TV.

Any helpful suggestions would be much appreciated.
