One or more pixels on the TV screen appear as dark, bright red, green, blue, or white dots

What you may be seeing is one or more of the greater than 2,000,000 dots that make up the composition of your LCD or OLED screen. These dots (also known as pixels) may appear red, green, blue, white or black.

High-precision technology is used to manufacture LCD and OLED displays to maintain a high standard of operation. However, with all LCD/OLED screens, regardless of manufacturer, there may be a small number of dots that do not change color. This is normal operation for LCD and OLED screens for all manufacturers. Most defects are only noticeable when an all-white or all-black picture is displayed and shouldn't be noticeable under normal operation.

Because a defective pixel or pixels is normal on all LCD or OLED screens, there's a high chance that a replacement screen may also have them. It's possible that the replacement could have more defective pixels or the pixels may appear in a more noticeable position.
