After lamp replacement, why is picture still green?

it seems like the green was not defective before you replaced the green. remove the red =no change in the screen color, that could be bad. put back red, then remove blue=screen color changed, blue is good, hope you got the idea.

Dlp tv color goes fuzzy and green

Its probably unrelated to lamp, take the lamp out, try it again and look into the lens, if its still very green the projectors electronics are failing. The projector generates pictures as 3 streams of info Red Green and Blue. It looks like the projectors red and blue electronics are failing, but the green is working.

The screen is green no color at all it makes aloud humming sound what is the problem we replaced the lamp last year

Do you have a cable box going to the TV and is this condition on all of the inputs or just one. Chances are you have standard video connection plugged into the component inputs.

If you have a (yellow/red/white) cable make sure you have it plugged into a connection on the tv that matches those colors because if you have a standard video (yellow) plugged into the Green then you will get a black and white picture.

If you are plugged into a component connection you will need a total of 5 RCA style wires. One will go from Green to Green, another from Blue to Blue, another from Red video to Red video, anther Red audio to Red audio and white audio to white audio.

The common mistakes made with this connection is the reversal of the RED video and RED audio which will cause the humming noise you spoke of as well.

Loud humming noise while rca Mod hd50lpw166 is running

There is a excellent chance it is the Color Wheel in the Optical Block. Some of the older models are not too bad to replace it, on the newer one though it is a major tear down. I would have a RCA Servicer come out to verify and get a estimate. Chances are do to the cost of Optical Block, it would be close to replacement of the Set.
Hope this helps,
