So I cleaned my lenses today, and some lens solution MUST have gotten into the housing (or something).

When the projector fired up, a foggy patch formed in the center of the lens. As such, the picture became milky, and some of the image was projected on the roof of the auditorium (not really noticeable to the audience, but definitely to me).

How can I deal with this?

Call up your booth supply dealer to arrange to have the lens to be sent to a repair place since the lens will have to be dismantled for either cleaning or element replacement.

For, it sounds like bare light went through the lens and burnt the coating on that one element which then it'll have to be replaced.

Good luck - Monte
