How to solve the malfunction of LED display?

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

If it takes power to power on the new screen installation, it may be that the control card settings are not scanned properly, or the cables are not plugged in properly (check the cables from the control card to the first board). This problem may also occur if the 5V power supply is connected incorrectly.

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

You can also try a DVI-connected monitor to see if the signal from the DVI output of the graphics card is normal. The general DVI interface resolution is 1024 * 768. The cause of the LED display's fancy display may also be a problem with the graphics card 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 full-color LED display are also provided for your reference:

1. LED electronic display is abnormal

Solution:

(1) Whether the parameter setting of the LED control card is correct, and whether any signal is transmitted to the electronic display LED control card;

(2) Whether the communication line is normal, check whether the LED control card has signal input;

(3) Whether the 5V power supply of the LED control card is normal;

2. Some screens of the electronic display screen are abnormal, such as black screen and flower screen

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

3.The LED display flower screen cannot be displayed

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

A. Problem with output

1. Check whether the line from the output interface to the signal output IC is connected or shorted.

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

3. Check whether the cascaded output data port between the last drive IC is connected to the data port of the output interface or whether it is shorted.

4. The heat dissipation of the case is not good, which causes the graphics card temperature to rise.

Solution: Troubleshoot thermal issues.

Check whether the fan is running normally, refuel the fan, clean up the dust in the case, and solve the problem after the heat dissipation is solved.

5, reinstall the system, graphics card or monitor does not support high resolution.

Solution:

(1) Restart the computer, press the F8 key continuously, in the advanced boot menu, select "Safe Mode" and press Enter to log in to the system, then enter the display settings under Windows, select the 16 color state, click the "Apply" button, and click "OK "Button.

(2) Restart the computer. In the normal mode of Windows, enter the device manager, 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. From simple to complex, starting from the basics of troubleshooting, we can definitely solve the problem. Really not possible, please ask for after-sales service support.
