This set has two 5 amp fuses on power board that feed the convergence circuit, did you test them?

I needed I can provide photo of that board, fuses are pico fuses and not glass.

Let me know and I will be happy to help you.

I have a sony kp-51ws510 projection tv, i replaced the convergence ic's and a pico fuse and then reset the convergence. The tv looks good except for a green shadow on lettering, also on the convergence...


Did you check the two pico fuses on the G board? Usually at least one will blow when the original ICs failed. I am attaching a pic that shows the 2 pico fuses on the G board.

Your Convergence ICs have failed. It is very common on rear projections. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.


Note if one STK chip fails, you replace both regardless.

My TV looks like it had permanent 3-D. Red Ghost


hello it sound like the convergance ic may be the problem these chips sit behind the tuner board connected to a metal frame called a heat sink they are soldered in. also you will have to check the resistor in front of the chips also check the 2 capacitors at either end it would be best to get a quote from and engineer good luck

I have sony model KP51WS510 with a red and green shadow also the color is off


Your TV most likely 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.

the tv needs to have a convergence done on it to realign the picture..the colors have to be set a certain way or it will show shadows and it will only get worse
