Projector 2300MP

I purchased a 2300MP projector three years ago so the warranty is out. The projector is projecting a green tint on all my powerpoint now. I have run the color test on it and everything seems all right.  I have even tested it with two different computers and I am getting the same green tint...so it must be the projector. I have tried to call DELL support but I waited on the phone for about 2 hours and only talked to one person who put me on hold to talk to another person.  You know the "old round around" game.   Can anyone help me with suggestions? Is this fixable?  I ticked at Dell and don't know if I want any more of their products.
