My Toshiba 42H83 has developed a color problem. The color blue is about an inch off the other colors, the picture looks like a 3d movie without the glasses. I have used the touch focus button on the...

Alot of rear projection t.v.'s have a convergence option in the menu on the t.v. There you can set the try to set the colors back how their supposed to. Mine has a cross in the middle of the screen and you just have to try to get all 3 colors to line up. Unfortunately, the actual lens inside mine has to be aligned so it doesnt work. Just something to try though, hope it helps.

You need to take the Toshiba remote that came with the machine and go into a menu area that deals with convergence. Here's what the manual says:

This TV used 3 separate TV tubes, red, green, and blue. The R, G, and B images are pojected onto the screen wheree they converge to form a full-color picture. You can see a clear picture only when the three images converge correctly. Corvergence my drift over time, or if yo move the TV. I you can see clear images on your TV screen skip this procedure.

Make this adjustment only after the TV as been on for at least 30 minutes.

Press the TOUCH FOCUS (auto convergence) button on the front of the TV at the bottom.
The TV will enter into the convergence mode and adjust the converge automatically (that's what it says.)


Press MENU, and the press < or > until the PICTURE menu appears.
Then press UP or DOWN to highlight CONVERGENCE.
Press < or > to display the Center Convergence menu

There's a lot more the book says, but, I can say from experience that you just go through the different sub areas of this menu and converge each color separately, and bingo, it's fixed.

Good luck.

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.

TOUCH FOCUS ERROR on Projection Toshiba TV

My 57H81 won't converge, plus I get the "touch focus error" message. I could get manual convergence of blue, but not red. Plus, during touch focus the red would not move horizontally

The convergence IC`s need to be replaced and the related low ohm resistors need to be checked for proper value.
