The color is "green"

Each filter intensifies its color and darkens others, especially the color opposite on the color wheel. They're not of much use in color photography, unless you want weird color casts, but they come into their own in black&white photography.
For example, a red filter intensifies red and darkens blue. It can make a sky look almost black, making clouds pop out. Similarly it can darken foliage. A green filter on the other hand will brighten foliage.
If your camera can take black&white photos, try taking pictures of a red rose with green leaves with and without the filters. With one combination the rose and the leaves will be the same shade. With a red filter the rose will be bright against the dark leaves. With a green filter you'll get a dark rose with bright leaves.
With digital photography you can achieve the same effect in postprocessing, but some times its easier to get the result in camera.

Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

mamacapizzib,

You have several problems going on here. First I will address the brightness which is interrelated with the color problem. You have no blue. Either the gun is dead or there is no drive. Since blue makes up about 20 percent of the color and brightness you will notice a decrease in brightness. The fact that you have only yellow and green says that the gun is not working. It could be the gun is bad or the video signal to the gun is not there. I have a tip at http://www.fixya.com/support/r6396176-projection_tv_troubleshooting which may be helpful in solving your problem.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

the color filters are burned from heat there are three small glass filters one is red one is blue and one s green They are in the light engine.I know I have the same tv and the same problem.you have to take the light engine apart or you could replace the light engine.a lot of plugs and screws to take out just to change three colored glass plates

hi verifies if you are connecting good the video cable i mean the red, the yellow, and the white, if this dont serve you, is because your tv is to old.

I would say the crt's are at the end of their life.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

You might have "color filter" settings. Turn the digital filters off. Here is what manual at p72 says. "You can take pictures using digital filters. The filters consist of color filters such as red, blue and green, a soft filter that produces a fuzzy effect. Color filters Eight colors, black-and-white, sepia, red, pink, violet, blue, green and yellow, are provided for the color filters. When you select a color filter in the Digital Filter mode, the display on the LCD monitor is filtered with the selected color, and the pictures are taken in that color."
