M115HD projects blue tinted screen

We are trying to troubleshoot why we have a blue tinted screen when projecting videos. We've tested with two laptops and 3 different connection cords (vga, hdmi, other). No luck. I've called Dell and they cannot tell me what the problem is nor can they refer me to a repair shop. Their solution, pay $500 and purchase a new projector. The projector is pretty new. At $500 a pop, it shouldn't be a throwaway device. I've gone through the menu on the projector to see if I can color correct. It's set correctly to the proper output connection and in movie mode. Can anyone assist?
