    Default Red pixel on display, its stuck or dead pixel? can it be fixed?

    Hello, i noticed that there is a red pixel on laptops Acer Aspire 5738 TFT Display, on white background the pixel is red, if i make background green, pixel is darker but i see its not black, its dark red. if i set blue color, pixel is dark but still can be seen as dark red, not black. so its basicly, its keep being red all the time not matter what i set on display, but its mixes with the other color thats suppose top be and creates darker red sub-color. As far as i know dead pixel must be black? So if this is just stucked liquid, it can be fixed somehow? If i set black color, pixel then is black also, no redness to see then. But logically - when its black - then black pixels is simply not black but turned off?

    So what u guys think? can i fix this somehow?

    Maybe its not displays but software issue? Like VGA or BIOS failing?
    VGA - Ati Radeon HD 4570 (512mb + hyper memory)
    Bios is Phoenix 1.16 (there is update for newer bios on acer website, but the warning about possible bios flashing failing kinda scares me. And this version seems works pretty well if we talk about voltages, temps and so.)

    My votes for classic dead pixel,if you press lightly on screen or from the back does it help,sometimes this will cure it for a short period of time.But i think its time for a screen replacement if it is in a area that will bug the heck out of you.

    Dead Pixels are Black doesn't light up.
    The issues describes Stucked Pixels.
    Some people claim you can massage them back to life but I am not sure about the effectiveness.
