Your Projector or Smart Board blinks orange for about 20-30 seconds then turns green or blinks green and the screen stays black.

This typically happens when either 1) a projector bulb has gone bad or 2) the fan has gone bad.

Recommendations: Consistently blow out the projectors and keep it clean. They get very hot and a lot of things can go wrong with anything gets to the temperatures that Projectors reach.

Hope this helped!
