We have a 3 yr old Dell 2300MP Projector that we just replaced the bulb in.

However, now the LCD projector only emits in black and white!  I've tried to reset the projector to factory settings, and even that has not work.

Any suggestions in regard to what the problem can be?   I've tried it with two different laptops, so I know the problem is with the projector itself.  When I go into settings, I can see the colors listed, but they are all in black and white - so changing the hues hasn't helped.

Please advise, and thank you.
