Mark,
There are several adjustments on module 53 relating to picture alienment, however these are not standard user adjustments that you may find on a computer monitor. Normally these only need adjustment after a component replacement.
However, before going down that route, I would ask if this problem has just occurred, in other words was the picture previously correct ?
The problem you describe is call "Pin Cushion Distortion" in the industry and can also be caused when the scanning coils on the neck of the tube have moved down the tube a short distance. This can occur when the TV has been moved a lot or been under some vibration.
So, I think I need to ask the following questions:-
- Has the picture previously NOT had the Pin Cushion Distortion ? if yes when did it first occur ?
- Has the TV been moved at lot prior to the problem ?
- Has the TV had any component chnages by a TV repair techician ?
Are you a technical person able to make internal adjustments if needed ?
