Hi, you`ve lost your convergence ic`s, unless your very proficient at solder work I`d advise you call a tech, will require removing 2 large IC`s and possibly a few small support parts, resistors, chemical fuses etc. Every place is a little different but runs approx. 300.00 at my shop, gl, video-tek

Picture Falling with arch


It is your convergence IC's going out, they cost about 40 $ for both, if you know someone that can solder, i would have them do it, once you see the new parts it is prity easy to find them on the board in your tv, repair shops usually charge 4 to 5 hundred

Color distortion and arched picture


Your TV most likely has one of two 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 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.

Please call a repair center. This is something you cannot repair your-self. It's usually around $200-400 for the repair depending on who does it.

Sony KP-57WS510 57 inch rear projection - Rainbow colors and arching


Same thing happened to me. I had to get it fixed. They said it was a "tube".

Now, my problem (7 months after getting it fixed) is that it suddenly seems a lot dimmer. I'm not 100% sure, and was wondering if there was some kind of diagnostic to run to find out for sure.
