  1. Pixels stuck 

 

Stuck pixels symptom is green dots or red dots on the notebook’s screen 

A nonconforming pixel can be a nuisance on LCD laptop, the pixels may be green or may be red without lighting up another pixel for the display.  It might possible that manufacturers may not replace the LCD for a pixel only. 

 Take a soft material like a cloth and gently rub it in a circular motion on the stuck pixels. This will light up the pixel if you find the exact location to illuminate the pixel, hold your finger for two minutes and now no more stuck pixel.
