    This might prove useful to some of you.

    Okay. Please take normal precautions. Unplug the project from the mains, work in a well ventilated room with plenty of light etc...

    Tools you will need.

    1 philips screwdriver with a reasonable medium head.
    1 can of compressed air.

    Instructions:-

    1/ Remove the 2 screws that hold on the lamp housing.

    2/ Remove the 3 screws that hold the lamp in place and remove the lamp. Put it somewhere safe.

    3/ Undo the four screws from the bottom of the projector and then slowly prize off the front facia and lid. Be carefull cause the lid contains a ribbon cable to the top controls.

    4/ Remove the four screws that hold the lens housing in place. You can turn the zoom to allow you access to the more difficult ones. Be very carefull with this part.

    5/ Use the can of compressed air. Making sure that it's perfectly upright and that no moister comes out the nozel. Spray the back of the lens, the inside where the DMD panel is and the bit where you took the bulb out.
    The technique I use is to start spraying away from the object until you can see it's only air coming out of the can and then direct it towards the projector.

    6/ Reassemble in reverse order.

    Your done.

    It was really simple. Only took me around 10 mins and i've got no dust blobs.

    Well worth a go.

    No piccies mate but it's dead easy.

    Seriously, it's not that hard. Just follow the guide and make sure your environment is dust free.
