I have a Mitsubishi DLP TV that is just over a year old. In the last week, I've noticed some fading of the colors. The whites are a bluish green. I've readjusted the PERFECT COLOR back to the factory settings, but still no luck. Does anyone have a suggestion as to what may be wrong?
Is the TV still "bright"? If so, then you may need to do manual color settings (via setup). Lamp may be going out too..or dirty. In dirty area? Then the mirrors (behind and below the main front screen) may be dirty or contaminated. Removal of Front Screen, not just the protective plastic, and cleaning all mirrors may be necessary.

Hi,do you hear buzzing,whirling or high pitch sounds? if you do it could be an issue with the color wheel If
the TV have the infamous blinking lights problem and you're replaced
your lamp without success, it's most likely a problem with your color
wheel. The Samsung color wheels spin anywhere from 6,000 to
15,000 revolutions per minute (RPM’s)--It is one of the few consumable
parts in your Samsung TV. The average life expectancy from our data
logging shows the Samsung color wheels are fairly reliable with a MEAN
average of 5-8 years .It could also be the DMD board this is how it works:http://electronics.howstuffworks.com/dlp1.htm One simple way to test if it is the DMD board it's to display thew menu,if menu is also affected that for sure what it is.God bless you!
my mitsubishi 73" set is 4+ years old. all of a sudden the color is all wrong. after a couple of minutes of clear picture the colors change--blue is green and red is yellow. a little while later everything has a red tint to it and there is a line going down the center of the screen. to the left the picture is still relatively sharp, but the right hand side is terrible. I'm hoping this is just the lamp.
I understand what you are saying, however the devil is in the details in reference to your problem. Let me explain, DLP Televisions use what is called "Color Wheel Technology". A wheel made up of primary and secondary colors spin at a synchronized rate with the Luminance Video signal and this along with the changing of the mirrors of the DLP processor creates the color that you see on the screen (This is a high level description, but it covers what is happening). Now what you are experiencing can happen if the sync between the signal to the color wheel and the DLP processor is off center, if the color wheel is out of alignment, or if the signal to the DLP is drifting. The bulb "light" is working but something happened to interfere with the sync between the color wheel and the DLP processor. I would suggest getting this looked at by a DLP qualified TV technician, because of the nature of this problem. In addition I would request that you have the technician do a certified alignment after the problem is taken care of.
