I have an analog Samsung TV which I bought in 1998. It is around 32
inches. The problem is the image keeps getting 'squeezed'--the sides
cave in and the image takes on the shape of an hourglass. In the past,
I would have this problem for like 10 minutes but the image would
eventually correct itself. Nowadays, the problem remains as it is.
Anything can be done about this?

Model # is TXJ2766.
