When a lot of WHITE is presented on the CRT, the picture collapses in width
somewhat and shows E/W distortion. Sound becomes muted. Pressing PP brings back normal sound. Under normal ops. the subtitles appear as "ragging italics". Any clue which component(s) to replace ? TYIA |

TYIA poor regulation somewhere along the line. start by changing the capacitors in the power supply and those near the line output transformer. line driver decoupler cap is possibly bad if you have line tearing. -Ben |

This may be due to bad regulation in the power supply, HV supply, pin amp,
and the scan amplifier areas. Start by doing an ESR test of all the capacitors in these areas. Replace all the ones where the ESR is out of specs. Chances are that this procedure will fix the set. Be ready to replace many capacitors in your set type. -- JANA _____ "Bram Stolk" wrote in message ...
