    They might know something in the Projector screen forum,
    be carefull you don't make the problem worse trying to get rid of it.
    I have heard you can get the screen replaced i think it was Razor who knows about it.

    It would be a stuck mirror i'm surprised it's blue i would have expected black or white.
    i would be tempted to paint it black with a felt tip pen it might make it less noticeable.

    If the blue dot you have is well defined, then I think it's probably a stuck mirror or perhaps a screen imperfection.

    Dust on the lens will usually look hazy and not defined to exactly a single position. With dust, you should still see the image being projected behind it.

    Hi steve & steveandlisabro

    There are companies out there that can sell you a replacement rear pro screen. If you are happy with the screens reflective properties etc then I would just contact Tosh for a replacement. If not you need a specialist av company that builds, designs for coroporate use. If you have no joy I might have a contact number for you. PM if you need a number. :)

    I don't see how, in a single DLP chip design, a stuck mirror could possibly produce any colour except white. Three chips are a different matter (but irrelevant here). Equally, I can't imagine what else may give rise to a blue dot. Strange.

    It is definately blue, the same colour as the light from the bulb!! also if there is no input into to the tv, ie if the screen is black I still get the blue light.Its about the size of a small knitting needle head.

    Could get an engineer out but dont want to be had !

    would I be able to fit the screen my self? and can I get just the top layer of the screen?

    Thanks for all your help!

    Aha... stuck mirror, then. Not fixable except by replacing the entire DMD. You are at the mercy of whatever the manufacturer's stuck pixel tolerance policy is.

    What you're saying definitely points to a stuck mirror. When you're changing the DMD, try to get them to change the whole light engine because you may have picture adjustment issues when just swapping the DMD module.

    This really depends on your TV's design - I'm sure it can be done on the Samsungs.

    Digital Micromirror Device or Digital Micromirror Array
    Try a felt tip pen black is less distracting than a bright blue or maybe a tiny bit of matt black tape

    No warranty???? :rolleyes:

    Well this can potentially cost you quite a bit to repair then. An entire light engine would usually cost somewhere in the region of about £1300 and once again, depending on the TV model.

    Perhaps St_ve's recommendations make more sense :confused:

    Sure this set was purchased through Ebay. Pretty sure seller stated screen was scuffed and had dead pixel. Amazed anyone bought it actually. Sure they paid in excess of a Grand for it. Not a bargain with those kind of defects really.
