Sometimes you can clear a stuck pixel with a gentle massage - just don't use too much force. Doesn't work if there's a sheet of glass in front of the screen, of course. Usually when I get a new screen, the first thing I'll do is check it out with a pure screen of each of red, blue, and green, which tends to show up stuck subpixels.
