Most smart televisions today have self-diagnostics in the form of a blink code, which is a flash sequence of lights from the LED indicator (usually located on the front panel) that helps identify specific issues or malfunctions within the TV. The LED blinks a certain number of times, pauses, and then repeats, indicating a specific error code based on the number of blinks.


This consolidated list provides an overview of diagnostic codes across several popular smart TVs as well as information about each brand. For specific troubleshooting, contact the manufacturer for support.
