You need to test the pico fuses on the convergence board, this are two small resistors at the base of the STK ICs on C board.
I think this unit mounts two STK 392-040 , you can replace with two STK 392-150 that blow less frequently. Ask the seller what ICs are supported on your set.
Each convergence IC costs about $8.

You can buy the STKs here:

STK392-110 - $5.99 each

Semiconductor STK392-150


See here on how to replace them.

There is a manual convergence setting. Press Menu until you see the option of convergence.
Save settings by pressing Power until you see Save Ok. You can exit the convergence screen by pressing the PIP button. 0 reloads the convergence.

It will periodically go out of wack again.

Picture on screen shrunk to about half size and color bands go around the picture - red, yellow, green, blue - almost looks like things are in 3D


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

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Your Convergence is off. Go through the menue to the CONVERGENCE and follow the on screen instructions.

Start with the RED gun and align each cross point starting with the upper left corner.

You will be pulling the red to match the green.

If the television shuts down during this process, it will reset the convergence and you can try again.

After you get the red gun perfectly aligned with the green, start with the blue.

follow the on screen directs and don't forget to store.

Use the remote for these adjustments.

I hope that this helps..
