Question about Sony KP-51WS510 51" Rear Projection HDTV-Ready Television
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 ?
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
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.
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!

Please check pico fuses in D board and confirm +22 & -22 volt supply to convergence ICs.
Fuse numbers are as follows...
