Color convergence messed up

Hi, The red convergence on my 57 H82 Toshiba projection tv is messed up. I've tried manually adjusting the color convergence but that doesn't work. Do you know what I should do next? Thanks!

You can get the convergence repair kit for your model that has both convergence IC and the six feed resistors at this link, The repair kit also has step by step instructions with pictures so you can do the repair your self. Heres the link.The 50H82 kit is the same for the 57H82, http://servicemanuals.vstore.ca/product_info.php/pName/toshiba-50h71--50h81-convergence-repair-kit/cName/convergence-repair-kits

Colors are separated red, yellow and green so picture is blurred


lgray1010,

Try using the Flash Focus to/or manually try to dial in the convergence. If you are unable to focus the TV using its convergence adjustment it's time to call the TV repair guy. Figure on between $250.00 and $400.00 USD.

Toshiba projection tv model 57H82 color convergence is off. tried the TouchFocus and get and error. tried manually but the red will only move up and down. i need it to move left and right.


OK, the problem is one of the STK392-110 convergence amps has died. It is rare that both die at the same time, so either vertical or horizontal will go out, but not both. Also look for an open fusable resistor near said IC.

Trying to manually fix color convergence on Toshiba 57H81


The convergence ICs and the six 1.8 ohm 1watt resistors need to be replaced. You can get the convergence repair kit for your model at www.tvrepairworld.com which has the Two Convergence ICs and the six resistors plus the CD with instructions on how to do the repair.

57HX81 projection tv,color is mostly red and picture is double.


This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300

Toshiba v43j22p 42" red shadows and lines over screen


6b5ee7e.png You may have a convergence problem. Here are some of the most common symptoms.

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.


You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

Green shadowing


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

Toshiba theaterview 50in rear projection tv


Look at it on the QVC channel where you have boxes with straight lines. If any of the 3 colors are bowed and 1 inch off, then it needs parts inside. If the colors are straight and only 1/4 inch off, you can adjust it. Using the remote, in the menus find convergence to adjust. Your user manual will explain it. At WWW.Toshiba.com you can download the manual if you do not have it.
