Your TV most likely has one of two 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 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.

Sounds like one of two things. either the Lamps are off focus or the picture settings are off have you tried to set the picture to different setting (movie, normal, and I can't remember the others off hand) but try that and see if it helps

My tv has lots of red and green. Faces are shadowed by a red outline. It occurs on all channels and dvd.


If problem does not fix by flash focus/ convergence adjustment in Menu then replace convergence output ICs on D board of tv that sounds defective and causing problem.
Comvergence output ICs replacement requires soldering work with proper tools and electronics knowledge/ experience, call local tech if you have no experience.

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. 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 Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, 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 TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects

The colors are separated. Images are blurry and


Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)
This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

There are three colors on the screen all make it blurry


the three colors in your screen are off alignment due to a color convergence failure. Usually due to damaged convergence power amplifiers(mounted on heavy looking metal heat dissipators)located in the D board. Replacing them usually takes care of the problem, sometimes there is further problems that arise from this failure some pico fuses located in the G board(power supply).

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.
