Replace STK convergence IC's w/OEM or better parts.Senior tech soldering ability needed. Ex==Steel jumper wires feeding b+ to conv. IC's need resolder to prevent call-back.Also, best re-alignment done in service mode==consult service literature.

Toshiba 42H82 Blue raster is bowed to the right in the middle to the rt. The auto convergence give an error.


You have convergence output failure. The output ICs will need to be replaced and possibly a small component like a resistor or two as well. Expect to pay a service company $350-$450 to resolve this.

Blue Convergence on Toshiba 42H82 42-Inch


it should just need new STK392-110 ICs which is actually not very difficult. You will need two ICs both STK392-110 and you can get replacements at the following link and they provide instructions on how to remove and replace Convergence ICs.
Heres the link.
