Philips CTV 29PT2252/56A (L01.1A chassis)problem:intermittent pincushion distortion

This Philips TV model# 29PT2252/56A exhibited intermittent increase in picture width with pincushion distortion and blanking of picture.
A visual inspection of the printed circuit board reveals solder crack on pin 1 of pincushion transformer on board location 5465/5464/5463.
Resoldering of the cold solder on the pincushion transformer solved the problem of  intermittent picture width and pincushion distortion.
