    On white scenes or a scene with clouds, there is a yellow spot or blob at the top center of my screen.
    I have cleaned the projector and air filter twice.
    The yellow spot still remains.
    This spot doesn't appear on dark scenes nor on the blue Sanyo countdown or initialization screen.
    I called Sanyo and a tech said it's dust.
    I called back and left a message on tech supports answering machine but no one called me back.
    I can tell you this, my next projector won't be a Sanyo.
    It will probably be a NEC dlp.
    Another guy on a home theater forum sounded like he had the same problem that I have.
    I think it was his blue lcd panel.
    My projector has a few more months of warranty.
    Here's a picture of the yellow blob that my projector shows:

    Here's a picture of what my screen looks like when it's defocused:

    My cheap digital camera doesn't always take good pictures but on the picture with the projector defocused, the artifacts onscreen are red.
    So, does anyone have a clue to what my problem is?
    Is it dust or a bad lcd panel?
    When I spoke with Sanyo tech support they said there is a charge to clean the dust out of a projector whether it's in warranty or not.
    Anyone with a Sanyo lcd in the United States, does Sanyo charge for in warranty projectors for cleaning dust out of the projector?
    Thanks!

    My video projector is ceiling mounted so it's kinda hard to hook a pc to it.
    Also, where it's yellow, I can see everything it's just happens to be yellow on some scenes. Specifically, light scenes and a sky scene.
    On dark colors its fine.

    I would guess dust, but I am no expert on the subject.
