In today’s society where full-color LED displays are popularized, some users will inevitably encounter problems such as led display screens. So how to deal with this kind of problem of LED display screen? Here is a summary of Deli display for your reference:
1. If the new screen is installed and powered on, the main reason is that the control card is set to scan incorrectly, or the cable is not inserted correctly.
2. If this phenomenon occurs after using for a period of time, in addition to the failure of the control card, the biggest reason is that the water enters the board and burns the chip or power supply.
If you want to solve this problem, you can try to connect a monitor with a DVI interface to see if the DVI output port of the graphics card has a normal signal.
Of course, the cause of the LED display blurry screen may also be a problem with the graphics card and driver. If so, we can try to unplug the network cable of the receiving card behind the display screen and press the debug button on the receiving card to see if the screen scan is normal.
Of course, the reasons for the blurry screen cannot be exhausted, and other reasons that may cause the full-color LED display screen to be blurred are also shared here:
1. The LED display screen cannot be displayed. Solution: Check whether the power supply of the electronic display screen is normal, whether there is a 220V strong power input, whether it will be low or high.
2. The LED display display is abnormal, blurry screen and the like. Solution: Whether the parameter settings of the LED control card are correct, whether the communication line is normal, and whether the 6V power supply of the LED control card is normal.
3. Part of the screen display is abnormal, such as black screen and blurry screen. Solution: Check whether the abnormal screen power supply is working normally, the signal transmission line is faulty; the single module of the screen is faulty.
It is worth mentioning the related issues of the LED display output:
1. Check whether the line from the output interface to the signal output IC is connected normally, and see if there is a short circuit or the like.
2. Check whether the clock latch signal of the output port is normal and whether there will be insufficient signal.
As long as the above points are done well, I believe that my friends will get a good solution to the problem of LED display screen.
Conclusion: It is hoped that the above information can help users solve their problems when they encounter the critical juncture of full-color LED display “hua screen”.
