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 repicture doubles and looks like 3d - 0667c5f.pngs 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.

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.

the convergence IC`s and associated resistors have to be replaced, do not repeatedly push magic focus or the alignment after the parts change out will take longer which of course means higher repair bill, good luck
