Panasonic Convergence problem HI..My TV all of a sudden started to act-up about a week ago..Its showing 3D images with blue as the double image.I tried to fix the convergence by going into the setup, but when i did this it would not do anything ...no line movement at all...also it wouldn't allow me to move to any another color other than green..The tv repair man came out and installed 2 STK-392-110 convergence chips. The tv still has the same problem. He said that he had to get a service manual for the Tv to put it back in focus manually...Its been 2 weeks and he still havent found his service manual....help!!!! please i need my TV football season is here...oh by the way i lost the original remote and im thinkingg that he could have use that to put it back in focuse...Is there a way that i can fix it manually, does anyone have a free service manual that he/i can use or you can just email me just that section on convergence setting travisswilliams@yahoo.com

The projection off my t.v. is off. Images over lap one another and I can see double of a single image. I this able to be fixed?


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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. In some cases the TV will also not show any video. 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 pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV 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 images.

Hi,
Please replace convergence ICs in tv, there are two big black ICs that has number STK392-110 mounted with big aluminum heat sink, replacement these ICs will solve your tv problem. Also check big resistor nearby these convergence ICs and replace if found burn mark or color faded.
On circuit board, IC location number is IC7001 and IC7002
Let me know if you have additional question.

The picture is showing a double image and is distored.


The problem you are refering to is more than likely a convergence problem. The convergence circuit in your tv is controlled by an IC (integrated circuit) stk392-110 and it makes the 3 colors (red, blue, green) line up/converge together to create a clear picture. You'll know when this part needs to be replaced because the picture you see is 3d looking and possibly bowed on the top or bottom or on the sides in any or all 3 colors.

Double image and 3d color

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.

  • 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 need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.
