Gene would be an authority on this. There are no adjustments on the back of the 
monitor that can correct this, although it might look better if you increased 
the width of the image maybe also the height. There may be pots accessible on 
the back of the set for that.

This problem is cause by dying circuitry and incorrectly adjusted coils on the 
neck of the picture tube. There may be some magnets that can be repositioned and 
the coil itself may be moveable on the neck of the tube.
Since these adjustments would need to be made with the set powered up, it would 
be much safer to live with the distortion rather than getting electrocuted. :)
