Problem 1: Abnormal display of the lamp surface.

If an area of the large LED screen is displaying all messy patterns that are flashing, it is likely a problem with the receiving card. To solve this, you need to check which receiving card controls the abnormal area and replace it.

Problem 2: Row of abnormalities with variegated color flash.
When the LED display shows a row of abnormalities with variegated color flash, it could be caused by a loose flat cable or damaged flat cable interface. You can start from the abnormal position and check the flat cable of the module. If you find any problem, either replace the flat cable or the faulty module.

Problem 3: Sporadic lights in the display.
If you notice sporadic lights in the display that are not bright, or the colors displayed on the whole screen are different, it is also known as black spots, bad lights, or dead lights. To solve this problem, you need to replace the modules with black spots, broken lights, or dead lights.

Problem 4: Tripping when powered on.
If the LED display trips as soon as it is powered on or during repeated operations, check whether there is a short circuit in the power line. You should also check whether the positive and negative power cord connectors are touching, and if there are any metal objects inside the screen.

Problem 5: A flashing square in a certain area of the display.
This is usually a problem with the module, and it can be solved by replacing the module in the abnormal display area of the block.

Problem 6: Large area of the LED display is not displayed.
If a large area of the LED display is not displayed and it is all black, first consider the power transmission problem. Check whether the power switch is damaged and there is no electricity, then check whether the flat cable is loose and the signal has not been transmitted. Finally, check whether the receiving card is damaged.

Problem 7: The screen sometimes freezes or blacks out.
If the LED display screen is playing videos or pictures, and the display area of the computer software is normal, but the screen sometimes freezes or blacks out, it could be due to poor quality network cable. You should replace the network cable with better quality ones.

Problem 8: Synchronize the full-screen display of the computer desktop with the LED display.
To achieve this function, you need to equip yourself with an LED video processor. After the video processor is equipped, you can adjust it on the video processor to synchronize the image area to be displayed on the large LED screen.

Problem 9: Disordered, staggered, or divided windows.
If the display of the software window of the LED display screen is normal, but the picture on the screen is disordered, staggered, or divided into multiple windows to display the same picture separately, it is most likely a software setting issue. Enter the software setting and reset the correct setting to solve the problem.

Problem 10: “No display system found” error.
If the computer network cable is well connected to the network cable of the LED display, but the software says “No display system found”, and the data sent by the software settings all fail, such as failed to send brightness data, it is usually a problem with the sending card. To solve this, replace the sending card.

The aforementioned are the frequently encountered issues in LED displays along with their remedies. Adhering to these solutions will enable you to effortlessly resolve any problems with your LED displays and maintain their optimal performance.
