Convergence On my KP46WT510, the far left line of manual convergence will not adjust enough . Overall the picture is still good,other than the left side with a little bit of shift. Do I need the complete replacement of convergence IC's or is there any thing else you can advise? Thanks

Solution: You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, pico fuses, etc. Everything you need to fix it yourself. Its an easy fix.

If you cannot align, the ICs probably need to be replaced. You can check the input on feedback resistors in front of the ICs with an ohm meter. Some resistors may be bad causing your problem. Usually you would need to replace the ICs and bad resistors and do a full re-alignment to fix.

With your TV in setup Use a small magnet to "move" the non converged Red, Blue, or, Green color lines "crosses" (each CRT will need to be adjusted in turn) by moving the magnet close to the offending Red, Blue or,Green color CRT yoke or, tube while observing the movement of the CRT color line "cross" in a mirror ( try several places near the tube and, several strengths of magnets:) a refrigerator sheet magnet works well (you can cut these with a scissors to make a better fit or, apply less magnetic "pull." by making them smaller (you may need more than one magnet per tube to fix each CRT's convergence) When you have each CRT tube's convergence right, apply some clear silicone adhesive to the magnet and, permanently affix the magnet to the now "fixed" CRT tube exactly where you placed the magnet to obtain the best convergence on the CRT.
(Do not adjust the "Green" CRT unless you must, as it is used as the color line to adjust other lines to)

Your TV most likely a convergence 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 are some photos of convergence problems.

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.

Convergence Problem and Contrast Adjustment


Have you checked all of the resistors inthe convergence circuit as well? If not, check them for the correct impedance.. Remember, you have to pull one side of the resistor out of circuit to measure it correctly. 
If all of the resistors are good, then you have to do a coarse convergence adjustment on the set through the service menu.. if you need the service manual for the convergence directions, I have one uploaded in the technicians corner of techlore.com

Sony kp46wt510 red only convergence bowed on top and bottom


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 projeciton 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 photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

CONVERGENCE IC ADJUSTMENT


My KP-46WT510 picture is out of alignment. There is no conversion of the red, blue and green pictures on the screen. They're off by about an inch of each other.
Some tech told me that it was the power control that was bad. I can see the picture, just very blurred.
Is he right? The tv was not move at all before this started happening.

Convergence Problem


sounds like 1 of the convergence chips are gone theres 2 of them and better off replacing both as the other would just go a month down the line there might also be a resister or 2 gone, the price for that kind of job is around 150 +vat.

hope this helps

Hello casey43_13 and nanac,
If the rest of the picture is great and only the edge are off, this might eliminate the convergence chip as been bad. This set is noted for bad convergence chip. The next step is that you need to do the convergence adjustment in service mode. This is a very complicated process. If you this you are up to the job of doing it yourself, please contact me by email. I will email you the procedures. By doing this yourself, you must understand that you could make the problem even worst.

Best regards
