Our 42" rear projection Mitsubishi tv worked just fine until suddenly one day last week when we turned it on and we don't get any red,organge, pink, or green colors. Blue and yellow shows up fine but everything else takes a brownish color. What could it be? Our tv is about 4-5 years old.
Sounds like your green tube is low or is bad

tube has a reservoir on the front of it with a fluid in it. this keeps the face of the tube cool.
this depends on how bad the damage is in the tv. in most cases we can reseal the tube and clean up the fluid 400-600.
Once you
take the tube out you will see where it leaked. The problem is that the
frame on the CRT that the heavy screws with springs are mounted on (that
hold the lens coupled to the CRT) is weak and they can bend. We have seen
several that have leaked after the customer moved the set. You can only
tighten them down so much because the frame bends. It is just stamped metal
and not welded at the corners to support the bend.
We remove the CRT, clean it all up, add a very small amount of RTV sealer to
the gasket, reassemble, let the RTV cure thoroughly and refill with coolant.
The extra sealer should prevent future leaks. Haven't had a recall yet.
Mits says replace the CRT...too costly.
You msut check the yokes carefully as well. If any coolant gets into them
you can end up with shorts there and a mess.
Clean the boards carefully and repair any corrosion damage. The coolant is
ethylene glycol and glycerine which is water soluable.

Have you checked out your cables yet? Or can you give me more info on how you have everything hooked up to your tv.
Are you watching your tv with one of your componat inputs? If so, the cable is bad.
