I have noticed this a few times on ota hdtv and dvd player (diffrent inputs). I get what looks like one pixel that goes bright orange, looks like a laser pointer except it does not move its always the same pixel, near the center. It only happens on some flesh tones, normally on someones face. Its not there all the time just randomly. What is causing this and what do I need to do fix it?

Its a hd1000u on a satin white painted wall, projected at 137 inches if it matters.

it's either some dust on your screen or you have a stuck pixel

turns out it looks like its some gloss white overspray on my satin painted screen.
