What you describe is called 'frame foldover'. It is unlikely to be expensive to repair in terms of components and engineer's time, trouble is, no one wants to pays to have TVs fixed these days as they can buy another relatively cheaply. That's why I left the trade several years ago. If you can find a TV repair shop in your area that is still in business it is worthwhile obtaining an estimate at the vey least.
