If you are able to do this, the switches woud be in the back of tv under the panel. Some tv's like most newer tv's are not adjustable except under main menu for color, tint, contrast and that is it.
This is when the convergance board needs to be replaced.

    The repair kit does work just fine. That is what most people are doing. Either buying a kit or replacing the board if there are a great number of faulty capacitors on the convergence board. People have seem to be having good luck with the kits and directions

The left side of screen is blurry.


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony2_bing.gif,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer2_bing.gif, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Color convergance from bottom of screen


PT-47WX53 - Visible Convergence Fault

You need to open the TV. Remove the deflection printed circuit board, access and replace the convergence ICs. Maybe some low ohm resistors are burnt as well. Change those too.

Make sure you do not do any damage to the connections or foil on the printed circuit board. Don't crack the board while breaking loose the ICs.

Also be careful to re-connect all the plugs and the inter-connects between the boards. Don't damage the plugs or connectors. Make sure you put them all back in the correct sockets.

After replacing everything and re-assembling, turn-on and stand back. Look for smoke. If no smoke, look at the picture and see how you have done. Use the auto-convergence if it is available auto-convergence should adjust the convergence grid to an acceptable level. Usually minor touch-up of user's manual convergence adjust screen is all you need to get a good picture. If the customer controls or auto-focus do not work correctly, you have not completed repair.

Do not attempt accessing and fiddling with the service screen unless it is absolutely required.

If there are still problems, get professional service help. Many of the ICs sold by the discount "Shopping Cart" One Stop Kit sites are bogus. They do not work.

Many times consumers buy the New and Improved" IC kits that are offered. Don't even think about it. All low ohm resistors will have to be changed. Many opportunities for damage and misadventure. Your Upgrade kit supplier is re-designing the TV that Panasonic spent millions of dollars perfecting.

Many consumers try to do a convergence repair and TVs become scrap. Check out the TV help blogs, most start with "I installed a set of ICs I purchased on the web, changed resistors as well, Now the TV has a poorer picture than before or it will not start."

If you have no electronics experience or training the chances of success are similar to do-it-yourself brain surgery in a Peruvian jungle with a sharpened arrowhead.

Call local service that knows your Panasonic TV. Ask for price before he comes out. If he won't give a firm estimate for on-site "convergence" repair, call someone else.

Call me in Canada, I'll give you a price.

Picture is blurry and concaved


This model kp-51HW40 uses two of the STK-392-560 CONVERGENCE IC CHIPS.

Usually just both chips need to be replaced and the set adjusted with the Sony remote---You can buy a pair of the chips on Ebay for less than 14 dollars plus shipping.

If you can do this repair you can save the set and a lot of money as most shops will charge 300 or more for this kind of repair.

I can give you general instructions if you think you can do it---there are places on the internet that sell
kits for this--usually very pricey and many of the included parts are not usually needed.

IF CONVERGENCE WILL NOT ADJUST: BOTH CHIPS NEED TO BE REPLACED.

There is a picture but it is blurry with a big yellow blur.


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 should be replaced. 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.

Too much red!


Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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.
