    My screen looks like it needs a good clean, top righthand side of my image is clean as a whistle, the rest is dirty. If i blur my vision you can see a smudge effect in the middle of the screen (probably about 8-9 inches in diameter) and various other dirty smudge effects on the right hand side of the image. I can see this all clearly on a white background. This all done to dust or a dirty lense on hte inside because ive cleaned the outside. Any Advice?

    The only comment I can make is from reading the forums it looks like the worst offender from previous models is the Sanyo Z2, then the Panasonix Ae500, and the least suseptable is the Sony.

    I think the forethought that Sanyo have done with the Z3 though is good where it has little holes under the projector and comes with a blower that you can use to blow dust blobs off the panels without even opening it up.

    *touches wood several times* :)

    My Sharp Z200E is dust-free. I have to say I don't recall seeing dust noted as a problem with DLPs, maybe it's to do with how they work perhaps?

    I have my first dust blob on the Sanyo Z3 after only 14 hours :eek: . I did a bit of drilling near the projector last night :nono:

    I will try the dust removal holes today and let people know how successful it is.

    Grass always seems greener on the other side.

    If you like LCD you will come back to a Sony.

    I'll save you the effort of searching for "dust blob and Z2" ;) ...

    Sadly the photos have been removed but this AVS thread describes the process and this thread on here has the key missing photo towards the end.

    Sanyo Z3 has six holes in it's base and a little squishy bottle thingy for blowing out dust blobs. Tried the little bottle and it did not remove the dust blob. Let it cool down and tried it again with a can of compressed air. No more dust blob :thumbsup:

    Whole process, including taking down from ceiling bracket took less than 5 minutes. That said I don't want to have to do this every 14 hours

    Thanks everyone, no mention of DLP and dust blobs are they less likely to get this problem? :smashin:

    Optics on DLP units are generally sealed to reduce the dust risk.

    The only area of DLP units that suffer from dust / smoke are the fans. If you keep the air intake and outake vents clean, you won't have any problems.

    ...and an any case, even if they did get some dust, the effect on the image would be entirely different (I won't go into the why, but it's to do with an entirely different way of generating colour).
