There are several 'recommended' fixes for stuck pixels, of which I can vouch for one. We have a dvd player in our car. it had around 15 stuck pixels. To fix it, I got a cloth and a pencil.
Put the cloth over the pixel (to stop the screen being damaged by the pencil) then press on the pixel through the cloth with the pencil. not with uber ninja force or anything, just firmly.
WHILE pressing, switch the power off then on again. You may have to try more than once with varying amounts of force on the pixel.
That fixed 14 out of the 15 pixels, we still has one stuck one. nehuz.
