Toshiba 57hx81 tv has a bow at bottom of screen and blue in color tried using toush focus & got error then tried to focus manually & couldn't get the bottom lines to focus all the way down


noted in the owners manual, if auto focus returns message "error" , it suggests to use manual convergence setting..failing that, is it resonable to suspect that the STK-392-110 (convergence (2)chips)are beginning to fail, bendt horizonital lines is the effect. you can check all the resistors and pico fuses (power board)near the chips for shorts, chances are they are ok. seeing that there is somewhat of a picture (kinda like 3-d). i would repaired it!.. while your there do the hyperboard repair as well by replacing the 10 caps with 16v@10uf. (causing a wavy vertical distortion effect).

57H81Toshiba Blue Line not straight


You have a bad convergence output IC in the blue vertical circuit. On the bottom side of the chassis you will see a " V " printed by the heat sink. You will need to unsolder the heat sink and the 20 pins on the IC to remove it. Replace with STK 392-180 (sanyo) if possible or STK 392-150. Looking from the rear the heat sinks are big aluminum finned rectangles. There are 2 heat sinks one marked H and one Marked V. Even though you have a horizontal line your problem is in the vertical IC. Be sure to use a liberal dose of heat sink compound.
