My sony KP-51WS500 is having ghosting problems with kind of 3D image with the three colors showing seperate image lines. How do I fix this and what is the cost.

The convergence is regulated by two ICs. When the convergence ICs become faulty you get colors not matching and shapes show kind of colored halos that may resemble a 3d effect.

The problem is fixed replacing the two ICs. The repair requires component testing and precision soldering experience and must be done by a technician.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• 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.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.

Common 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.

Press the Majic Focus button on the front. If that doesn't fix it then the convergence ICs may be bad.

If colors are skewed and will not adjust in the customer menu---you have a CONVERGENCE circuit problem.

This model (KP-51WS500) uses two of the STK-392-560 convergence IC chips. I just got home from fixing a similar model with the same problem.

Parts cost on Ebay for the chips and such is going to be less than 30 dollars total. Shops are going to get 300 or more for this kind of repair---and some will not do it in your home---the repair takes about an hour--I have done hundreds of them here in people's homes.

If you have questions or need advice, reply to this posting and I will try to help.

had tv that did the same thing after three years but they were green cost me 300 bucks to get it fixed and the guy said every 3 to 5 expect it

This is a convergence problem that can be as simple as poor solder connections on the convergence ICs or defecive ICs. If you can solder you can repair this yourself, Let me know if you wish to attempt the repair and I'll provide additional details and instructions.

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.

Solution #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.

my sony kp-57wv600 is showing a ghost of the image in all three colors.. anyone no how i can fix

Symptoms shows TV has problem of faliure of convergence out ICs. (2 ICs in TV) and need to be replaced.Let me know do you want to repair it at your own? ...
... if yes, it is necessary to have experience of TV repair and basic electronics knowledge.

If your tv is Sony KP-51WS500, then its rear projection tv and problem seems in convergence stage.
Please confirm model number to guide you further.
