Personally, I would have the technician come complete the job he started since you paid for it. However, if you feel you must do it, you will have to purchase the service manual to do it properly and completely.

Got new STK392-040 chips and picture is still distorted. Manual convergence still won't alligne all colors.


the 183 is entry into the tech menu===you need to test all the low value resistors around the convergence chips(only 6 or 8) and they will read low and a resistor with NO reading may be your problem.

Also these sets use a pico fuse going to each chip--either right with it or back at the source----know what a pico fuse looks like"

One half of picture is distorted


to create the total geometry in the tv is needed a system called Convergence.Convergence amplifiers are damaged in this unit, magic focus cannot work because magic focus works to level computer and controls the amplifiers damaged. this repair is for a technician because an adjustment is needed after the amplifier's replacement.

Convergance Problem??


Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.
