I can only give you advice based on my knowledge of DLP TV 3Ds. Samsung DLP Link makes the picture extremely red on my set when 3D is active. I've heard that Mitts DLP Link makes the picture extremely green. The solution is to not use IR glasses, as they do not block out the DLP Link signal. DLP Link glasses should fully block the signal (which causes the tint) and your blacks should be black, not tinted green. All other colors should also look normal as well.
What type of glasses are you currently using? IR, RF, or DLP Link?
Getting the correct brand of DLP Link glasses should fix your tint issue.
