How to solve the problem of full-color LED display screen flower

How to solve the problem of LED display screen failure? There are many reasons why the full-color LED display screen cannot display normally. Here is a summary of how to solve the problem of full-color LED display screen failure.

　　If the new screen malfunctions after being installed and powered on, it may be that the control card is set up to scan incorrectly, or the cable is not plugged in correctly (check the cable from the control card to the first board). This problem may also occur if the 5V power supply is connected incorrectly.

　　If you suddenly discover this phenomenon after using it for a period of time, in addition to a control card failure, the most likely possibility is that water has entered the board and burned the chip or power supply.

　　You can also try to connect a monitor with a DVI interface to see if the DVI output port of the graphics card has a normal signal. Generally, the DVI interface resolution of a Lingxingyu card is 1024*768. The cause of the LED display screen may also be a graphics card problem or a driver problem. Try to unplug the network cable of the receiving card behind the display and press the debug button on the receiving card to see if the screen scan is normal.

　　In addition, other reasons that cause the full-color LED display screen to be distorted are also provided for your reference:

　　1. The LED display screen is distorted and cannot display

　　Solution: Check whether the power supply of the electronic display is normal and whether there is 220V strong power input

　　2. The LED electronic display screen displays abnormally, with a distorted screen

　　Solution:

　　(1) Whether the parameters of the LED control card are set correctly and whether there is any signal transmitted to the LED control card of the electronic display screen;

　　(2) Check whether the communication line is normal and whether the LED control card has signal input;

　　(3) Is the 5V power supply of the LED control card normal?

　　3. Part of the electronic display screen displays abnormally, such as black screen or flowery screen

　　Solution: Check whether the power supply of the screen with abnormal display is working normally; the signal transmission line is faulty; a single module of the screen is faulty.

　　A. There is a problem with the output

　　1. Check whether the line from the output interface to the signal output IC is connected or short-circuited.

　　2. Check whether the clock latch signal of the output port is normal.

　　3. Check whether the cascade output data port between the last driver IC is connected to the data port of the output interface or whether it is short-circuited.

　　4. The chassis does not dissipate heat well, causing the graphics card temperature to rise.

　　Solution: Eliminate heat dissipation issues.

　　Check whether the fan is operating normally, add oil to the fan, clean the dust inside the chassis, and the fault can be eliminated after solving the heat dissipation problem.

　　5. Reinstall the system because the graphics card or monitor does not support high resolution.

　　Solution:

　　(1) Restart the computer, press the F8 key continuously, select "Safe Mode" in the Advanced Startup Menu, press Enter to log in to the system, then enter the display settings in Windows, select 16-color status, click the "Apply" button, and click the "OK" button.

　　(2) Restart the computer, enter the device manager in normal Windows mode, delete the graphics card driver, and restart the computer.

　　The above is the introduction of the causes and solutions of the full-color LED display screen. From simple to complex, starting from the basics, you can definitely solve the problem. If it doesn't work, please ask after-sales service support.
