Sony kp 51ws510 convergence problem

HI,

My Sony KP 51WS510 had a convergence problem, all 3 colors were mis-positioned, and I had replaced 2 convergence ICs, but the problem still there, I was wondering maybe the convergence board needs to be replaced, any idea where can I buy the convergence board ?

Thanks
Steven

    i have the same convergence problems with my sony kp51ws510 rear projection tv...has anyone contacted sony to see why there was no recall on this poorly manufactured or badly design tv?

    I have replaced the two convergence ic's . On one of them i seem to have pulled the copper from the hole as one pin will not solder to the circuit board. Anyway, i tried to fill it up and hope for the best.
    turn on the set and picture is fine but after a few minutes red shadow lines. I checked 5 yellow 3.25 amp pico fuses under the fins and are fine. How do I find the resistors or any other fuse that feed the convergence?
    Please!

Your TV most likely has one or more possible problems.

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 shouldsony kp 51ws510 convergence problem - 2c07611.pngd. This is a common problem.

2c07611.pngSolution #1

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.

In order to aline convergence you have to get into Service MENU for tech only.Codes to Enter Service menu. Also have you ck the pico fuses that feed the ICs they look like resistors but are not green or yellow 6amp/ 7amp pico fuses if one or more is open you can not control convergence settings. If the picos are OK ,then you need to get into service menu to set convergence. /will have to find SMC for sony will let you know asap!

My tv has lots of red and green. Faces are shadowed by a red outline. It occurs on all channels and dvd.


If problem does not fix by flash focus/ convergence adjustment in Menu then replace convergence output ICs on D board of tv that sounds defective and causing problem.
Comvergence output ICs replacement requires soldering work with proper tools and electronics knowledge/ experience, call local tech if you have no experience.

Same problem as achilles_08...different colors on screen


This is a convergence problem that can be as simple as poor solder connections at the convergence ICs or defective ICs. Try esoldering the ICs first. If that fails to resolve it, replace them. These will be large black ICs attached to a heat sink and marked STKxxx.
