Toshiba 43h70 convergence

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

This tv the convergence board are dead.Any colors R,G,B mis alignment,don't matches any colors lines.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts are dead,must be replaced to solved convergence problems.The Shop will cost u $300-350 for parts and labors.

on the signal board. you need soldering iron and lead. make sure you won't short the STK pins..good luck :) and also check pico fuses.

check your soldering,look for any burnt resistors,open traces,small elecrtrolytic caps

Hello, its very possible there are other color alignments thats out of ajustements and certain color lines will affect each range of alignment and
you will need a tech to come out and check the control unit on your set.

Go over your soldering and make sure none of the pins are connected by a solder splash.and that all plugs are seated and that no picos are open...

You need to replace both convergence ICs numbers STK392-110 . You can order replacements at this link I am enclosing. They provide free installation instructions and offer free on line instan messaging while youre doing the repair. I am one of thier Techs. This job takes about 45 minutes from start to finish. heres the link .

If the blue colors will not line up, and the blue appears to sag inward from one or more sides, then you can bet that one of your convergence IC's has either cracked loose or burned out. The IC should be resoldered or replaced and the convergence realigned by someone experienced with projection TV convergence circuits.
