    Can you be clearer? I was thinking of changing the STKs on the convergence board.

    Is there a manuel way to do the alignment?

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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

Looking into the "convergence" menu may be what is needed. Hopefully it is simply an alignment problem brought about by time and handling.

    The simple manual way to adjust is under #4 convergence in the menu. If you can't fix this issue with this procedure perhaps replacing the chips would be a good idea.

Why does my tv have one blue, one red and one green line at the top of the screen but no picture?


The CRT inside the TV has gone bad. You can either find the make and model of the CRT and replace it, or get rid of the tv and buy another one.

Coulor distortion at the top left of the screen


Hello jordan ashe,

This is an indication that the green CRT is having a convergence problem. This might be caused by the convergence amplifier or by the CRT. Does the rest of the picture look OK? and in addition can you supply a picture of your TV so as I can see what you are seeing and develop a proper diagnosis?


Thank you,

Part of the picture is out of focus


Typical convergence problem. Its 2 ICs that start with stk standing up on the printed circuit board, and this is not a repair for the layman. No insult intendedb there is a lot of High Voltage inside these sets neven when they are unplugged. You also need to unsolder ansd resolder the IC's when they are replaced.
