Try seeing if the color wheel is off-center or off-balanced. For Rear projection tvs there are allot of small delicate parts that should be touch only by a professional repairman with the correct tools to avoid voiding warranty or further damaging machine.

Picture has become distorted, especially towards the side of the television. The colour filters line up towards the middle of the television, but become distorted towards the sides.


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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

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 - 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.

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 solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Sounds like a convergence issue with your RGB colour channels - probably need to get it serviced and have the convergence tuned.
Unlikely you can do this yourself.

Red convergence way off


Hello,
I had the same issue as you pretty much exactly and so do others right around this last few weeks so I am thinking that this is a common problem with the product itself.

You can fix this pretty quickly with the link below. I bought it and it resolved the issue.
