I found that the easiest way is to send the computer back to the company you bought it for and demand a replacement -- but if you're past the warranty this may -- or may not -- work for you.
If your LCD screen has a stuck or dead pixel , it's usually malfunctioning because the liquid in the liquid crystal display (TFT LCD) has not covered the whole screen. This can be easily fixed.
