I have a Toshiba Model 42H82 With distorted & shaky Picture


If its shaky, zig zag, or torn looking, etc your hyper module has gone out. You can get the repair parts and instructions on www.TvRepairKits.com

If it just looks 3D or wavy...and is not moving around...its your convergence that has gone out.

The convergence going bad again on my Hitachi 51swx20b


Sounds like loose solder on the chips. Either that or they are failing. You can save money next time by doing it yourself with a kit from www.TvRepairKits.com

Shaky picture


You have a bad electrolytic capacitor on the convergence board...i think it is a 16volt 220mf....located near the 9volt reg. You will need a cap checker and some one who can replace it. Been a long time since i repaired one of these ageing sets. But that is exactly what you are looking for.

My red s off in my pictre causing ghostng


you will need to replace both convergence ICs they are both STK392-120 and you will also need about four 6.8 ohm 1watt resistors as well. You can get replacement ICs and resistors at the following link and they provide free instalation instructions with pictures so you can do the repair yourself.

Replaced Convergence Board...then...Blue shawdow appears


Maybe the new board was bad, or the B+ that feeds the convergence board is bad., This is where experience comes to play I'm afraid. Good Luck.
