How to solve the problem of sudden LED display screen failure

if the new screen is powered on, it may be that the control card settings are not scanned correctly, or the cable is not inserted correctly (check the cable from the control card to the first board with high measurement accuracy), and this problem will 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 board is flooded and burns the chip or power supply

you can also try a display with a DVI interface. First, check whether the DVI output port of the graphics card is normal. Generally, the DVI interface resolution of yangbang card is 1024*768. The reason for LED display screen failure may also be the problem of the graphics card or the drive problem. Try to unplug the cable of the receiving card behind the display screen and press the debugging button on the receiving card to see whether the screen body 6. Assembly width - the width scanning of the leaf spring product within the clamping range of the U-bolt and the sliding part of the support is normal

in addition, other reasons causing the flower screen of full-color LED display screen are also provided for your reference:

1. The flower screen of LED display screen cannot be displayed

solution: check whether the power supply of electronic display screen is normal, whether there is 220V strong current input

2. The display of LED electronic display screen is abnormal, and the flower screen


(1) whether the parameter setting of LED control card is correct, Whether the signal is 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) whether the 5V power supply of LED control card is normal

3. Part of the screen body of the electronic display screen is abnormal, such as black screen, flower screen

the clamping length of the sample is short

solution: check whether the screen body power supply with abnormal display works normally; Signal transmission line failure; A single module of the screen fails

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 at the exit of the exhibition features is normal

3. Check whether the cascade output data port between the last drive IC is connected with the data port of the output interface or is short circuited

4. Poor heat dissipation of the chassis leads to an increase in the temperature of the graphics card

solution: eliminate the heat dissipation problem

check whether the fan operates normally, add oil to the fan, clean the dust in the chassis, and solve the problem of heat dissipation

5. The system is reinstalled, and the graphics card or display does not support high resolution


(1) restart the computer, press F8 continuously, in the Advanced Startup menu, select enter "safe mode" to log in to the system, then enter the display setting under windows, select the 16 color state, click the "apply" button, and click the "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 full-color LED display screen blooming. The problem can be solved by troubleshooting from simple to complex and from basic. It's really not good. Please provide after-sales service support
