    How small can dust blobs be?

    Is a green mark spanning several pixels (circular and about 1cm wide on a 6ft+ screen) likely to be a dust blob on the LCD?

    I read somewhere on this forum that someone had one the size of a tennis ball which is why I ask.

    if you can see picture through the blob--- then it's likely to be dust

    I can see through it, but despite two cans of air trying to remove it (yes I took the case off ;)), it stays!

    If you defocus your projector (one way or the other) a dust blob should eventually come into sharp focus - whereupon you can see its shape more clearly. This may give you a clue as to what it is.

    Hi,
    I had a dust blob the size of a tennis ball,very frustrating to remove the pj from the ceiling open it up give it a blast with canned air.put it back up and still find the bugger in the middle of the screen.
    I lost count how many times i did this,used 3 cans of air,I sent it back to panasonic in the end and they sorted it out for me.
    It does'nt matter how much air you blow inside, there are some places it just wont reach.
    hope you get it sorted out
    cheers Dean
