You will need to replace both STK392-120 convergence ICs and about four of the 6.8 ohm 1 watt resistors. The following link has the replacement ICs and resistors and they provide free instalation instructions with pictures.

I have a 52 in. tv magnovox the color on the screen is not as clear it has alot of red and the color scheme is medium


6d3e6c1f-c991-4dcf-aa4f-930b9d111d87.pngBelow are two of the most common problems encountered with projection TV sets.

Problem #1 - CONVERGENCE PROBLEM

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 Projection TV sets and a fairly simple DIY fix.

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 - 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 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 solution

CONVERGENCE 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 TvRepairKits.com

Their kits include a step by step instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Problem #2 CRT Fluid is Cloudy

Projection tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around video.


What you will need to do is replace the coolant and clean the crt. You can get a repair kit from TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.

Hello, my tv looks 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.

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

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 - TV may also make a chirping noise.

Colors Misalinged


You have what is known as covergence problems. Ok to begin with. 1 Go into customer menus goto SETUP do you have the "CONVERGENCE" option. If you do not the the likelyhood is you have the fl231 fuse problem and if you can solder and get it i recomend it a simple repair. ok if you have that option then try going in and autoconvergening if that didnt work try manual the red and blue convergence. if in the manual red and blue the crosshair didnt move then you probably have convergence power board problem if only one moved or just move a up and down or left of right then it might be a amp board issue. the other problems it could need a simple factory alignment.

Colors red and green overlap


Covergence is off... Check convergence and see which color will not move in the convergence settings... That is the STK that needs to be changed out...

Adjust color convergence automaticly


I hate to tell you but if the colors are not aligning the way they used to is because the set has developed a problem know as a convergence problem,you should be able to align the colors (red,Blue)but if they are not going in is because the covergence IC's are going bad,If you are familiar with electronic service you can do some of the work yourself but sometimes still does require the help of a servicer to do the aligments from the inside,if you are not too familiar be safe and call for assistance.
