As long as you replace both STK392-120 and about four of the 6.8 ohm 1watt resistors it should go rather smoothly, its actually a easy repair. You can get replacement ICs and the resistors at the following link with free step by step instruction with pitures. Heres the link.

Hi Eric,

First of all, thank you for contacting Fixya.com regarding on your TV problem.

I've suspected a convergence chips failure not the power supply board issue in this kind of symptoms. To confirm it, locate the convergence board inside the set, it has a Sanyo convergence chip STK392-110 that are mounted on the large heat sink. This board has a LED (light emitting diode) that will light up once the board gone to malfunction. Turn on the unit and then check if the LED will lit after the shuts down. If yes, then I would advice you to replaced both convergence Chips and check the resistance of the resistors in line with the +25V and -20V supply of the chips.
Let me know if the LED at the convergence board does not lit to continue our diagnosis... Check also the LED at the power supply board and on the deflection board(this is where the flyback transformer is located)

Have a nice day!

Goodluck and take care!

Kind Regards,

It appears to be convergence issues. Red, green,


Projection TV2_bing.gif 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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith2_bing.gif, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D2_bing.gif
  • 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 - 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.

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 flash2_bing.gif 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 solution

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

Green and pink shadow on my samsung 55in proj tv what can i do to fix it. i all ready fixed red and blue line but green is way off and i dont see any way to fix it


hi, this is the early signs of convergence board chip failure. you will need to replace this board in order to correct the collaboration feature. the convergence is responsible for regulating the RGB stream in you set. if it is malfunctioning, you will not be able to regulate the red blue green streams.

Red and blue ghosts


You most likely have a convergence chip bad. In our shop, when we are working on projection TVs, we find that about 80% of the repairs we make are the same problem you are having. You need to replace the convergence chip ( there are 2 of the same chips on the convergence board, and I suggest you replace both ). If you are going to attempt the repair yourself you'll need to remember to use lots of heat sink grease so you don't have the same problem again. Also, try to get original parts, as there are times that the after-market ones don't work well. As a precaution, always remember to unplug the set from the wall before you do any work on the set. Good Luck
