Color convergence "whacked out"/blue shadow to right side

Your TV most likely has a convergence failure. ( common problem )

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 are some photos of convergence problems.

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.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Not focused

Please! Stop using the magic focus now!
There are internal parts that have failed and this requires attention by qualified personnel.
The more you hit the magic focus, the more the proper calibration points will go off the mark, since the computer only knows that the calibration is incorrect, but is unaware that the parts that DO the calibrating are defective.
Sometimes this will make the repair more difficult, since a major maual recalibration may be necessary if the registers "rolled over".
If no one had touched the magic focus and just called for repair, the set would just need the parts. Once replaced, the set would look normal. Yours will require a few more steps.

Focus

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.

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.

TV PIcture and Sound Shut Down

it would appear its shutting down in a protect mode
its possible its a convergence circuit problem or something on the deflection bd
but it most likley will require some assistance from a tech that is used to working on this type of set
if you noticed when it does come on that the colors are all off line then suspect convergence circuit trouble the the green leds tell you what source is still alive there is a chart in the cabinet that will correspond with each source voltage that can lead you to tracking it down if you know what to look for and have the tools to do so

TV Has 3D Look Hitting used to fix but not anymore

The convergence IC's are bad. (They are probably STK392-110) If you look at the connections, yuo'll probably see little rings in the solder where the pins come thru the board. Your problem probably started as bad connections and has now led to complete failure of the IC's. Replace them both. Look for burned resistors

Age of tv?

I purchased mine from Circuit city back in spring of 2002 as a display model that they were no longer selling. So I would assume 2001 which would be almost 8 years old. Excellent tv!

Blue ghosting

yes you will need to replace the two convergence ICs stk392-110 you can getreplacement ICs at the following link with free installation instructions. You will also need six convergence resistors. Leave them a email with your model number and they will tell you which resistors are needed for your model.

Convergence problem

did you replace the six convergence resistors with the ICs? as Hitachi recommends replacing the six resistors when the ICs are replaced as the old ICs can harm the resistors and they will need replacement.
