Advertising LED full-color electronic screen flickering reasons:

1. Driver loader error.

2. The network cable between the computer and the screen is too long or the network cable is faulty.

3. The sending card is broken.

4. The control card is broken. Check whether the small light on the control card is on or off, otherwise it will be broken.

5. Whether the connection line between the power supply and the control card is short-circuited.

6. The output voltage and current of the power supply are unstable, and the power supply with control card should not bring too many boards.

The solution to the flickering LED full-color electronic screen of advertising:

If the entire screen is distorted with dots and shadows, it's usually a problem with the driver loader. Check the driver loader again, it is indeed impossible to uninstall and reinstall. Another possibility is that the sending card is broken, and the sending card needs to be replaced.

If it flashes irregularly, it is usually a system frequency problem. Replacing the system or adjusting the setting parameters can basically solve it! If it is blinking, it may be a problem with the graphics card driver or the resolution setting of the sending card. Another possibility is a power supply problem (insufficient power supply, information clutter, electromagnetic interference). When designing a PCB, pay more attention to the wire diameter of the power supply and signal traces, as well as the production process of the PCB. Adding a few capacitors to the module also has some improvements.

If the text is flickering (there is an irregular white border around the text, the irregular flickering, the text disappears and then disappears), this is a problem with the graphics card settings. In the display properties, cancel the "show hidden shadows under the menu" and "smooth edge transition effect", you can solve this kind of problem.
