Stuck Pixel Fixer

In short Flashing rapid colour changes over a stuck pixel can sometimes free it, by driving the latched sub-pixel through its full range until it starts responding again. It works on stuck pixels only — the ones showing a constant bright colour — and never on dead ones, because a dead pixel receives no power and nothing displayed on screen can change that. Ten to thirty minutes is the usual advice, and the honest version is that if an hour makes no difference, more time will not either. Two warnings. Do not press on the screen, despite how widely that advice circulates: it risks permanent damage to the layers under the glass, and any improvement people report is usually the panel flexing rather than a pixel recovering. And on OLED, keep sessions short — a few minutes at moderate brightness mirrors what a television's own pixel refresh does, while hours at maximum brightness ages the emitters unnecessarily. Success rates are modest. This is worth trying before a warranty claim, not instead of one.
