There are many reasons why the LED display screen suddenly goes black or flickers during gaming. These include power supply problems, such as unstable or faulty power supply; connection problems, such as loose or damaged signal cables; hardware failures, such as damage to the control card, sending card, or LED module; software setting errors, such as improper resolution settings or driver loading problems; and environmental factors, such as electromagnetic interference or extreme temperature changes.
Solving these problems requires checking them one by one and taking appropriate measures to restore the normal operation of the display screen.
