SOURCE: Out of focus

Rach, if it doesn`t move from green to red to blue in Magic Focus then there is a problem with the convergence IC`s and probably one or more support resisters. These components will have to be replaced, questions? ask away, BMW Rider

SOURCE: my magic focus

Without knowing make and model of set. i would have to guess that on of your output resistors in your convergence curcit has failed. there is a possiblity that one of your stk amplifer ics is bad

Lookslike the picture is in 3d and when i try ti use magic focus


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

Will not show red color in picture, magic focus shows red though


You have a projection light element out. I had the green element go on mine. I had a service agreement so a repair tech changed it.

Magic Focus does not work.


Convergence issues usually resolved by changing convergence output amplifier IC's.....Original STK392-110 should be replaced
with upgrade Stk394-160E Hitachi part # CZ 01341,change both
for reliability.....check B+ feed resistors for over-heating....T.
