That sounds like it could be a color wheel. The color wheel controls the color on your picture since the DMD chip only creates a gray scale picture. You'll need to do a little more trouble shooting. Color wheels can cost around $100. They can be replaced on your own, but it's kind of a pain to get to.

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.

Had my tv for some time now without any problems.we purchased a new one and gve the toshiba 42inch rear projection to a friend,they had it a week and the screen went green,the sound is fine.we have thought...


If the screen is green then it is not the bulb. Most likely the color wheel is not turning. There is a rotating wheel that has Red, Green and Blue color segments. If the wheel is not moving then it will just show one color. This is something that can be fixed but requires a repair service center.

I suddenly lost the color on the screen and no manual adjustments seem to work to restore it.


I'm assuming that you have tried all the color temperatures, the full color setting, the full tint range and the correct input/colorstream to no avail. The only thing left that you can do then is to try to reset it - Menu, Picture, Reset button on the remote.
If even this has failed then the defect is in the tuner - you will have to call a repairman to replace it.

The Red and Blue colors suddenly have come out of alignment...it's like one shadows the other. I no longer have the original remote and am unable to move all the way through the menu to determine if this...


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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. This is called convergence.

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,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with 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

Black and White


on a low signal input to the set the first thing you loose is the color, then it goes snowy and then just snowwhite in a snow storm or all blue with no sound.

check your cables for no shorts and loose connections,
sometimes the color killer control inside the set in the color circuit has to be tweaked alittle.
