The LG panel is an advanced product that contains millions of pixels. In a very few cases, you could see fine dots on the screen while you’re viewing the TV. Those dots are deactivated pixels and do not affect the performance and reliability of the TV.
A pixel outage (Dead pixel) can be defined as a stuck pixel is a bright dot of color that fails to update when neighboring pixels change. Stuck pixels are most noticeable when the rest of the screen is black.
- Dark Pixels: These are caused by dead transistors and cannot be fixed.
- Stuck pixels: A partial sub-pixel defect from the RGB film layer being cut improperly and cannot be fixed.
- Bright Pixels: This is caused by a malfunction in the transistor that allows light through all of the sub pixels, or none of them.
Please note that in most cases, the pixel can not be fixed, but there is always hope that a few steps may revive the pixel.
Note: Please note none of these are created by LG, these suggestions if done incorrectly could damage your device and it will not be covered under warranty.
