    I have a projector that is clear in the middle but blurry around the edge of the image. I have already cleaned the board and the lens. What would cause this?

    Hi jlittleton,

    Thanks for posting on the Support Community and letting us know the issue and steps that you’ve done already.

    I suspect that this may be dust ingress to the projector or a possible issue with the lamp.

    Please could you try another lamp in the projector that is known to work on another model and see if you have the same issue?

    Kind regards,
    Promethean Support

    Yes I have tried a known good lamp. How do you fix dust ingress?

    There is not a user-serviceable method for performing a deep cleaning of the Projector’s internals.  We would recommend reaching out to us via e-mail with the serial number of the projector and pictures of what it is displaying so we can advise further.
