SOURCE: convergence problem

We need a better description of what you mean by shadowing. However I am assuming: 1. You mean it ''bleeds'' off to the right when you have something with a hard red/blue drive. 2. When you turn the contrast and color down a bit it gets better. unfortunatly I cannot tell you how to fix convergence, but I can think of some other possibilities. In this case the red/blue emmision of the crt is dying off and going into saturation when driven hard. To fix, replace with a new picture tube/crt. In some cases you can get a little more life out of that tube (with a watchable picture) by having the screen, focus, cathode bias, and drives slightly readjusted. It will take someone with experience in doing these adjustments on a weak tube to get it looking as good as possible. Given the construction of the cathodes (guns) in that crt, only a very low level crt reactivate should be tried on it. The hard rejuv most crt testers give is highly likley to completely destroy the cathode on that crt.

Replace STK convergence IC's w/OEM or better parts.Senior tech soldering ability needed. Ex==Steel jumper wires feeding b+ to conv. IC's need resolder to prevent call-back.Also, best re-alignment done in service mode==consult service literature.

Pink and green outlines (double edges) around the images on the screen


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

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 pics of convergence problems.

Common 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.

I have an8 year old toshiba 57h81 projection tv. I am seeing pink and green double shadows around images. Any thoughts? Cost to fix? Thanks.


Have you tried the convergence procedure from the on screen menu? If the red and blue don't want to adjust when you do this then you most likely have bad convergence IC chips which can be replaced for about $50-75 in parts and $200+ in labor. If you have experience with electronics and soldering you can do this yourself. If not  leave it to a TV tech.

This is a very common failure on Projection TV sets. Its called a convergence failure. Here are some common symptoms.
  • 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.
The other common problem is cloudy lens fluid. After many years the coolant in the blue and green lens will become cloudy and cause the screen to look dull, red/orange, bright white, etc. You may even see halos around objects on the screen.

This would be a convergence issue you can run the convergence setup that is in your user manual if that does not work you are going to need service.

The words on the screen is doubled or trippled.


Go to the picture control menu and turn the color to minumum so that you are watching a black & white picture. Do this to determine if the color offset affects the overall screen or just the lower corner. If the center is off, go to the convergence adjustment menu and align the red and blue onto the green as described in the owners manual. Some models also allow you to align the outer edges as well. If the bottom is still bad you may have a problem in the convergence circuit. If the outlines are not seriously bowed or distorted a minor convergence toutchup by a qualified technician should correct the problem, otherwise parts are involved and the repair is considered major.
