    Sorry, complete noob to projectors. Just wanted some help.

    Ive bought a 2nd hand Hewlett Packard DLP VP6121 and done the sheet of paper test. Well, the screen is COVERED in dust.

    i was wondering what the best way of removing dust was for a noob. Is there a service in london that people know of as i'm not really comfortable taking the thing apart.

    Any help much appreciated.

    Get a can of compressed air and hose it down!!

    Alot of people dont like doing this as they may be unaware of any loose parts in their PJ but I have known a few folk that have used compressed air to clean dust away and it has worked a treat. In fact someone here done it only a few days ago.

    It will save you the cost of service!

    there are two specs of dust that when projected look like two light patches right in the centre of the picture. Theres no discoloration, it just looks a bit like lens flare or something. At first I thought it might be light reflecting off a picture frame or something but the piece of paper test showed a lot of filth.

    So with the compressed air do I just spray it through the vents and stuff? How do I get near the lens

    Just spray it anywhere you see a gap, its amazing how it gets through and cleans things up.

    Hmmm, wouldn't the compressed air push dirt and dust into the tiny componants where they will get stuck and be completely unable to remove???

    Its not water, its the propellant which is methonal i belive, wont harm the system if its switched off since it evaporates in seconds at room temperature, what does happen is the can get VERY cold and can cause frostbite

    ok, well the compressed air as made things a hundred imes worse. there is now hundreds of tiny white specks all over the screen. I didnt tilt the can and i gave it a good blast at first to make sure it was clean. Its obviously sprayed some sort of residue somewhere inside though and now the picture is unwatchable.

    Time to send it away for a proffessional clean methinks. Any suggestions on where to look for a service? i live in london.


    GAAAAAaaaaaahhhhh
