Panasonic HDTV PT-56WX42 convergence problem with red and green

Can anyone guide me on how to fix this myself I have tried to adjust the convergence1 and convergence2 with out any luck on convergence one it seems that when i try and allign it, it is not moving. I called the local shop to get it fixed and is about 400. they said I needed to get the red and green chip replaced. Can someon help me find out what chip exactly I need and how hard of a job do you think it is? I am mechanically inclined so feel I will be able to do this job on my own. Has anyone done this?

The colors on my tv doesn't line up right. It has a 3D look and i tried to converge it. It will not let me do it. Its a panasonic HDTV PT-47WX42, PT-47WX52, PT-53WX42, PT-53WX52, PT-56WX42, PT-56WX52

set uses two of the STK-392-110 chips for convergence.

Both will have to be replaced.

I have start to finish step by step instructions for this repair based on me doing it in hundreds of these sets.

If you want the instructions, do you have a email?

Panasonic rear projection-red convergence-moves horizontal only!?

The convergence ICs have failed. You will need to install a convergence repair kit. You can get the convergence repair kit for your model Panasonic from which contains both of the Convergence ICs , the associated resistors and the cD with detailed repair instructions.

Pt-47wx49e convergence problem

I just replaced the 2 convergance chips, but it did not seem to fix the problem. I then tested all the resistors that feed the convergence chips anf there was a 2.2 ohm fusable blown. IT was R7050 on mine. That seemed to fix it so that I could adjust all the colors through the convergence 2 screen. There seems to be a slight bow near the bottom when you look at the c2 screen, but not noticable when you are watching a picture. Since I got this broken, I am not sure how perfect it should be.

If anyone can send me the service manual, I would appretiate it. Thanks.

PT-47WX53G green convergence and wave on bottom of screen

Had same problem with Red. Could not adjust. Funny broken lines. Found this link:

Replaced the ICs. Was disappointed at first 'cause it was still all bowed out, but then realized that the Convergence 2 "target" can be changed with the number keys. Working thru 1-9 and going back to readjust as necessary adjusted each one into perfect alignment.

Problem solved. TV works great.

I should add that while I am reasonable technically adept, I am a software geek and never soldered before... hardest part was getting up the courage to dive in and do it myself. Glad I did.

The tube should be ok its the IC's regulating the convergence is your problem . A tv repairman should be able to repair it fro around $250.00 - $300.00 or less depending on who you call. Good luck

Red and Green Spots

Not a fix for do-it-yourselfers, but check with Panasonic as there is a new fix. Requires tech to come and reprogram the eprom (I think).
Cheaper than a new optic board.

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 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
