Convergence on lower half of the screen is off, green arc appears


Your TV most likely has a Convergence Chip 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.

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.

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.

Do not open anything until you. Go to menu on your remote find convergence and press the volume button to the right go to manual and press right again. you should see a bunch of rectangles, now you should also see a set of red cross heirs press the #2 to move cross heirs up and eight to move down numbers 4 and 6 will move left and right and 5 will place the cross heirs back to the center once you have chosen the selected section to adjust line up the magenta with the other colors using the channel and volume buttons these move the lines up down left to right adjust all lines until they are white. i do not know how to switch from magenta to green or blue but this should get you started on the right track with out having to replace anything. good luck! if you figure out how to switch from maqgent to green or blue please post it so that I may adjust mine as well tahnks

I am having a shadow/double image problem only on the left side of the screen


Yes its called the Convergence ICs there are two of them they are mounted on a huge heat sink with the part number stamped on them they will have a STK number such as STK392-110. they have 16 pins on them there are two cost around 10 dollars each, you will also need some Heat sink Compound. Just look for the largest heat sink in your tv and thats where they will be. However if you can move both red and blue colors up,down right and left its probaly not your ICs. Do the colors move in all directions? If so you probaly just need to do a multipoint convergence adjustment.via of the service menu. Hope this helps. let me know if you need anything further.
