Understanding the Black Screen Issue

Experiencing a black screen on your LG TV can be perplexing. Essentially, a black screen occurs when the display fails to show any picture, despite the TV being powered on. This issue can be temporary or persistent, and the solution often lies in the nature of the problem. At its core, a black screen may indicate a failure in the TV's ability to process or display the image signal.
