SOURCE: conversion problems

What model number. Likely your conversion amplifiers and a resistor or two have gone out. Most Toshiba's use STK392-110 which can be replaced with STK392-120. You always replace both even if only one was bad.

Bowed in at top and bottom and colors are separated


You have a convergence issue. First question in customer menu under setup do you have the convergence optioin? IF you DO NOT then chances are you have the fl231 problem. check under my profile in the tips and trick section. IF you do have the option try autoconvergence. if this fails(goes red screen then you might have a convergence power supply problem.

Pt-47wx49e convergence problem


I just replaced the 2 convergance chips, but it did not seem to fix the problem. I then tested all the resistors that feed the convergence chips anf there was a 2.2 ohm fusable blown. IT was R7050 on mine. That seemed to fix it so that I could adjust all the colors through the convergence 2 screen. There seems to be a slight bow near the bottom when you look at the c2 screen, but not noticable when you are watching a picture. Since I got this broken, I am not sure how perfect it should be.

If anyone can send me the service manual, I would appretiate it. Thanks.
