OK so we had our ceiling projector making some noise. I figured it was a dirty fan, so late last night (like an idiot) I sprayed the compressed air can into it. Well heard a very loud pop. I am assuming it's the bulb that blew, could it have been anything else? I am going to order one, but wanted to make sure it's nothing else. I can plug power into it, and the power light just flashes, there again, I assume it's doing that because of the bulb. HELP
