The IF modules that were used on these and the large screen Pye CTVs (725/731/741, etc) were nororiously troublesome. Sometimes we fixed them successfully by resoldering all the joints on both sides but it often worked out more cost effective to fit one of the replacement modules with a SAW filter. Either way, it earned us some pennies.
