How to solve the LED display screen failure? The full color LED display screen can not be displayed normally for a variety of reasons, we have summarized some methods to solve the full-color LED display screen blurred.


If the new LED display screen is blurred when powered on, it may be that the scanned type of control card are not settings correctly, or the cable is not plugged in (checking the cable from the control card to the first LED module). This problem can also occur when the 5V power supply is connected incorrectly.
