    Hi
    I am a little new to this game so please bare with me if this is a stupid question. I have just bought a second hand Sanyo PLC SU22N lcd projector, which generally I am pleased with. The problem I have is that there is a blue dot on the screen when the projector is warm. When first switched on it is not there but appears after about 10-15 minutes. Is this a dead pixel and if so can anything be done about?. Thanks for any help

    It does sound that way.

    It's not uncomon for them to be heat related either.

    Can you see it with any picture if black, white, moving etc?

    Most LCD's have at least one I'm afraid it is a problem with manufactering. at least it wasn't a green one.

    Good news is it is uncommon for new ones to apear.

    Thanks for the reply. The dot is most visible on a black screen but is invisible on white
