    see here you should spray the air in where the gold ribbons are, remember keeep the can upright and it should be ok, the best can air i have used is the ones from jessops with the screw on metal tube, it seems the air blast is much stronger and is more effective in removing dust

    might be dust on the red panel, to check if its dust adjust the focus on the pj if its dust the blob will com into focus while the rest of the image will be out of focus

    Just done my 700 as i got fed up waiting for panasonic to come and pick it up, really simple to do just be carefull, i used a compressor to blow the dust out, i think id left the dust there too long (waiting for panasonic) and it may have burned in to the panel as i can still see a slight marking where the dust was. I would advise u blow it out as soon as possible to avoid permanent damage to the panels.

    its one i bought for car spraying and using air tools, a bit overkill for blowing dust out of a projector but miles better than canned air, cost 200 quid from machine mart, u can buy a lot of canned air for that.

    I seem to have had the worst luck with my pj's over the years but i still say go for it, even with all the problems ive had i could never give up my pj and go back to a conventional tv, well not till they make them "90. Buy one u will never look back.

    Miles better for spraying and inflating tyres, but the air from a compressor will always be dirteier than that from one of the aerosols. Even with a water trap (that isn't fitted to DIY compressors as standard), tiny particles of rust etc. from the air receiver can still get through. I certanly wouldn't use my compressor on a projectors LCD panels.
