Picture stretched or "squeezed" inward from sides - black section on side.
My parents gave this TV to my son. They bought another one at the suggestion of the repair shop person who didn't even look at it.
Basically the picture looks like somebody grabbed the middle of each side edge and pulled them in toward the center leaving a convex black vertical bar on either side and compressing the middle portion of the remaining picture. The TV will then eventually shut itself off.
I'd especially like to know if this is a picture tube problem. The picture tube is still under warranty but my folks didn't take it in to the shop because they were told that if it turned out to be a non-picture-tube problem, they'd have to pay for the diagnosis AND it would be more cost effective to buy a new TV then to repair.
Incidentally, my son has used the tried-and-true repair method of whacking the side of the TV chasis and this will sometimes correct the problem until the TV is shut off manually and then the problem will usually reoccur when the set is turned back on. Often, when he smacks it, the set will just turn itself off.
I opened the chasis to check for any obvious problems and attempted wiggling various wire connections and circuit boards and nothing presented itself as the obvious source of the problem.

Your TV has dry solder joints in "Pin Cushion" area, Its part of Horizontal deflection stage in TV and it requires resold work. A tech person will understand above technical advise easily. Need further info, let me know please.
You may have to refer to the instruction manual for details.
There should be in the menu set-up an option to set the aspect ratio for the different broadcast modes. Normaly, when viewing a 4:3 picture on an HD 16:9 set, the sides will be cut off, otherwise the picture will be stretched or compensated.
Sounds like you may have caps going bad . Adjusting may tend to only stretch the the picture too much . Also when you say horizontal are you saying the top and bottom are closing in ? If yes then your problem is in the vertical section . If side to side then check the horizontal section . Good luck
Some of the problem could be a weak or damaged picture tube - especially if it encountered rough handling in the move. Other possibilities are bad capacitors in the power supply and deflection circuits which are common with this aged set. No adjustments come to mind that could permanently fix these symptoms.
