That is a common problem with large screen crt sets, the east west correction circuit has failed but some times caused by dry joints on the circuit board. If not DJ's you need a circuit diagram to be able to fix it as Sony uses sometimes an unusual way to achieve east west correction.

It sounds like the customer needs to adjust the hourglass effect knob, holmes.

Probably a cold solder connection in the pin correction circuit area. I have also seen capacitors failing in the deflection and pin areas that cause this.
