I have a WT46805 and the color is fine for standard video input, but the when same video content is sent in through the HD input, the resolution is fantastic but the color is almost a monochromatic green. ...

While you are in the HD input look in the TV's menu, I think it is in video settings for a setting for RGB or Y, Pr, Pb. If it is set to RGB you will get that green picture. If you are not in the HD input that setting will not show up in the menu.

Mitsubishi wd 52525 lost greens and blues. only colors on screen are red hues.

This the classic symptom for component input wires being crossed. Check color coding on tv input and signal sourse. Green,Blue and Red wires must correspond. If ok Is the color off on the tv menu also. If so and wires are ok replace light engine.

The color seems to be off. No red, and lots of purple. This is a Toshiba 57H81 wide screen big box tv. It was purchased in 2002.

Could be a bad board within the tv but it is sometimes the source input meaning it could be dvd player, cable/satellite box, etc causing the loss of color but it is unlikely. I have one of these tvs and they use red green and blue projectors to reproduce the colors so when the red projector fails then you get purple which is green and blue colors combined without the red. I have found it to be sometimes a bad connection inside the tv and I found insects such as roaches inside others. Using extreme caution when opening the rear cover of any tv due to dangerous and fatal high voltage. You might find that simply cleaning out the inside of tv and reseating all the connectors might resolve your issue otherwise you would have haul this tv to a repair shop where you pay half the price of a new flat screen lcd for just repairing this tv which will probaly have another color go out next month.

TV picture is red.

Normal color picture is composed with 3 colors R-G-B (Red-Green-Blue). Picture turns Red means: Missing Green and Blue colors (many reasons: bad contacts, projector tubes dead, and other...). Try to give some "tabs" to diagnose ... I don't know what is the type of your Projection TV, how long you owned it, to have more idea.

Fuzzy/ distorted tv pic

Projection sets have two very common problems.

The first common problem is convergence

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 more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Green Picture

You can, but it's a hard fix. I'm a repairman, and I don't even like to do this one!

Toshiba 57H81 Color Problem

sounds like your green tube is set to high.
take the front cover off and the plastic cover under that
you will see a black box about 6x6 with 6 controls one is for focus the other is for intensity
here a guide for sony but yours should be close.
