Many people do not know how to solve the LED display screen, because many people think that the LED display screen failure is a big problem, they do not have the confidence to deal with it well, but also afraid of their own hands, will accidentally touch a switch or component caused by the flower screen is more serious. In fact, the LED display is not as delicate as everyone imagines, although there are many reasons why the small-pitch LED display screen cannot be displayed normally, do not be afraid, and then follow the Constant Color Optoelectronics Xiaobian to overhaul the LED display screen fault:
The newly installed LED display appears on the flower screen:
The newly installed small-pitch LED display has just been installed on the power-on screen, which is mostly because the SCAN of the LED software control card setting is not correct, and the other is that the cable is not plugged in or the cable is not inserted in place.
If you want to solve this kind of problem, Hengcai Optoelectronics Xiaobian found a monitor that can try to connect to the DVI interface, observe whether the DVI output port of the graphics card is normal, and eliminate the signal output problem caused by the fault of the graphics card. Although the display card technology of LED display manufacturers is mature and the cause of failure is less, this step of operation is still necessary, after all, it is a troubleshooting method, step by step to find the cause, do not miss every link.
In addition, the reason for the small-pitch LED display screen may also be the problem of graphics card and driver. If it is really a graphics card and drive problem, Hengcai Optoelectronics Xiaobian suggests that you can try to replace the network cable of the receiving card behind the display with the debugging button on the receiving card to see if the display box scanning is normal.
After using it for a period of time, it is found that the LED display screen is flowered:
If it is because of the use of a period of time after the discovery of LED display screen phenomenon, most of the reasons are control card failure, control card failure, most of the reason is LED display board water leakage caused, damage chips, circuit devices or power supply.
1. The LED screen flower screen cannot be displayed. Solution: Check whether the power supply of the display is normal, and whether there is a strong power input that causes the power supply to be low or high.
2, LED electronic display display is not normal, blurry and not clear and so on. Solution: Check whether the parameters of the LED control card are set correctly, whether the communication line communicates normally, whether the cable is loose or poorly contacted, plug and unplug the cable signal line, and clean up the dirt of the cable contact.
3. The display screen is not normal, such as black screen and blurry flower screen. Solution: Check whether the local power supply is working normally and whether the signal transmission line of the screen body is faulty.
4, the above operations have not solved the LED display screen problem, just look at the next big move. Output related issues.
Check the problems related to the signal output: Check whether the line from the output interface to the signal output IC is wrong, whether there is a short circuit, etc. Detect whether the clock lock of the output port has an abnormal signal problem and whether there will be insufficient signal.
Hengcai Optoelectronics Xiaobian believes that as long as friends do the above points, the problem of small-pitch LED display screen can almost be handled.
