There may be an open fuse. The typical fuse for the application is a 3-amp, and may not look anything like your typical fuse. If you have sucessfully replaced the parts that you indicated, the convergence should be very close to what it was before the failure. The fuse may look like a small rectangle of black or white plastic with a wire through it.

Sony KP-51HW40 Convergence issue


Can you adjust the convergence by the convergence menu without going through the service menu? The settings through the convergence menu should save automatically. Have you replaced the convergence ICs? If so the settings should save, if not the D board will need to be replaced or at the very least rebuilt. Let me know if you need further assistance with this issue.

Selective "non-convergence" issues


Sounds like to may have a yoke loose on a tube. If it's not that, you may have somehow damaged the convergence board. Look for any cracks in the board. If you find any, solder across the beaks and it should be fine. Good luck and I hope this has helped in some way

The color keeps going out


The repair tech used cheap parts or did not replace both convergence chips.


Problem #1: 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.

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 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.


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.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.
