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

that's got t o do with personnel preference and room lighting , but as a general rule adjust color hue's till the edges of a white color object on screen has just lost its primary color edge

the older projection TV's actually have voltage numbers for the service tech to adjust them too , but im not remembering seeing any in the LCD manuals

the lenses are accessable by removing lower back of unit,clean them with a damp paper towel-wipe them off with a dry one.put back back on unit.
screen/focas controls are in front of unit.remove speaker grill remove black cover using phillips screwdriver.you will see 2 sets of controls.one row is focas.one row is screen controls.red,green,blue.turn each focas control slowly to get the clearest picture for each color.screen controls are touchy(if you turn then too high unit will shut off)if the black and white picture was good i would not adjust screen controls.if it was bad turn blue and green screens down all the way.picture is now red turn green up until it turns yellow then turn blue up until it turns white

mitsubishi will rebuild the chasis for $200 with a 6 month warranty

It sounds like you TV is overheating and the video is suffering and the lamp is overheating as well. Also, if your TV is over 2-3 years old, the mirrors (behind and below the big front screen) desperately need to be cleaned. Clean all filters and fans as well. (Look on side and behind the unit). Is the TV in a "hot" environment and/or dirty environment? DLP TV's are NOT sealed units. They need to be cleaned every few years to work well to have a good, clear, bright picture.

The green CRT's (color picutre tube or color wheel, or ballast) will need to be tested for replacement.
It is quite common with these tv's

You will need an ohmmeter and or voltmeter and test each component for currency and accuracy

TRake the fron grill off and the front board 6- screws on my 65inch there are three adjustment knobs one of them wil adjust the huge
one the whole screen,if not that,I have heard mold growing on and the inside of the blue bulb because it runs the coolest out of the three.

there may be the possiblity of loose dvi cable between chasis and optical enngine. this is a cable much like a montor cable. it has two screws that tighten it down. reseting this sometime help

anytime you connect componet signal (green red and blue)to regular video inputs (yellow) end will have same effect. make sure that if you are using component signal from dvd player you have to connected to component input in the set.
component signal will use green red and blue for video and red and white for sound.

REPLACE THE CONVERGENCE IC (OR IC'S). A FUN JOB I CHARGE ABOUT 200 FOR.

sounds like bad capacitors on the FMT board need replacing that is a common fault with the first generation DLPs There are 3 bad capacitors.
