    Just wondering what a dead pixel is and how you can tell and also if you have one and you have just bought the pj what you can do about it. I have noticed a bright blue dot right at the bottom of my screen, i cant even see it unless i look face close and it doesnt even show in any film ive watched, is this a dead pixel.

    I had that on my CS3..it turned out to be a spec of dust. It only showed up in light scenes but it didn't last more than a few days..

    If you go up close to your screen, you will see a fine grid of coloured dots each surrounded by a thin black outline. On a white image, each dot will be white. The black outlines are what is known as the "chicken wire" effect.

    Each coloured dot is an individual pixel.

    If your bright spot is exactly the shape and size of one of these pixels then, in all likelihood it is a bad pixel.

    On the other hand, if your blue dot covers a larger area than a single pixel and is more diffuse, it is more probably a dust fibre that has lodged itself somewhere in your optics.

    A bad pixel cannot be fixed. A dust fibre can be removed.

    to be honest i have to go face close to see it, when i step back a foot i cant see it anymore and theres noway anybody could ever spot it, so is there any point in doing anything about it, no metter whats on the screen in terms of colour or picture it doesnt show and i had to look close up nose to wall to see it.

    Good answers Roland.... I have one on my 10ht which only shows up against a white backgound on the rhs near the edge but everything else is perfect so if I argue for an replacement I KNOW some other problem much worse will happen!!
