    Hi Guys,
    With some help from a friend,I had a go at cleaning my Sony vpl12 LCD projector yesterday.
    Few times the air can blew out both air and liquid while spraying the panel. I managed to get rid of the dust blobs and the pj is working ok but my wife is having a go saying that the picture quality is not as sharp as it was before I took it down for cleaning,I think she may be right.
    Now I am paranoid that I may have got some propellant inside the lcd panel while cleaning it.
    Will this cause a long time damage to the pj? :oops:

    You've taken the reflective coating off the panels.......Maybe

    As long as you used a non-alchol and non-solvent based solution and lint free cloths, there shouldn't be a problem.

    Foam cleaners, meths, duster, wet wipes etc will have damaged the panels.

    Can you see the "grid" of the LCD pixels clearly and in focus?

    Any damage you may have inflicted (seems unlikely in fact) wouldn't be even across the whole image - there'd be patches.

    So, to what extent is it "not as sharp"?

    - evenly all over? Have you rechecked the focus of the lens? If it is as sharp as it will go and you can see the pixel grid clearly, then, unless something has changed about the input signal at the same time, it's probably a figment of her (your) imagination.

    - unevenly in patches? Maybe you did damage it. But it does seem unlikely with an air duster can.
