      I attempted to clean my projector with compressed air. I stupidly sprayed the compressed air in the projector while it was running. Since that time, the screen is very dim. I tried another bulb and it worked the same. I cleaned the mirror by the bulb and no results. I am afraid that there is residue on the back of the lense. When the compressed air was sprayed in, a flame came out. What do I do to get that residue off?

      Please contact our Technical Support Team with the serial number of the projector in question; they would best be able to suggest the best courses of action to take with this unit.


      In the meantime, please reference Article 10757 on our Knowledge Base for suggestions on how to properly maintain our Promethean-branded proejctors.
