    Stuck Pixels = White (or other)
    Dead Pixesls = Black (off)

    You can buy a replacement screen from an online store or ebay. Or, you could send it to sony and have them replace it for like 100 bucks.

    A dead pixel is a defective pixel that remains unlit on an LCD screen or a CCD or CMOS sensor in a digital camera. The term "dead pixel" is often applied to other defective pixels, but there are also separate terms. A permanently lit (white) pixel is called a hot pixel, and a pixel that stays on a solid color (red, green, or blue) is known as a stuck pixel.

    A stuck pixel is a common pixel defect on LCD screens. A stuck pixel will be most visible against a black background, where it will appear red, green, blue, or any combination of the three (including white, although solid red, green, or blue, are the most common.) Each pixel on an LCD monitor is composed of three subpixels, one red, one green, and one blue, which produce the visible color of the pixel by their relative brightness. A stuck pixel results from a manufacturing defect which leaves one or more of these sub-pixels permanently turned on.
