During the assembly process of LED electronic screens, various faults may be encountered. Here are some common problems and their solutions: https://www.sostron.com/product?category=2

Possible reasons and solutions for failure to load:

A. Make sure the control system hardware is powered on correctly (5V). Here is a purchasing guide for LED display control systems.

B. Check and confirm that the serial port cable used to connect the controller is a straight-through cable.

C. Check whether the serial port cable is intact and not loose at both ends.

D. Set the correct product model, transmission method, serial port number, and baud rate according to the LED display control software and control card.

E. Check whether the jumper cap is loose or fallen off.

F. If the above steps are invalid, use a multimeter to measure whether the serial port of the computer or control system hardware is damaged.

Possible reasons and solutions for communication failure:

Check whether the serial port cable is intact and not loose at both ends. D. Set the correct product model, transmission method, serial port number, and baud rate according to the LED display control software and control card. E. Check whether the jumper cap is loose or fallen off. F. If the above steps are invalid, use a multimeter to measure whether the serial port of the computer or control system hardware is damaged.

Solution to the system prompt "Please connect the LED display controller":

Connect the LED display control system hardware to the computer, and connect the HUB distribution board to the display. Enter "Set Screen Parameters" in "Settings" to set relevant parameters. Here are the LED display specifications. Close and reopen the software and make sure "Connection successful" is displayed above the software.

Reasons and solutions for a few seconds of bright lines or "blurred screen" when the controller is powered on:

This phenomenon is a normal test, and bright lines or "blurred screens" will appear when the power is turned on. Within 2 seconds, this phenomenon will automatically disappear and the LED display will enter normal working status.

The meaning of automatic or manual brightness adjustment:

Brightness adjustment refers to adjusting between the darkest and brightest the LED display can display. How to adjust the brightness and contrast of LED display? Automatic brightness adjustment automatically adjusts to predetermined brightness according to different time periods. Manual brightness adjustment is implemented by the end user through control system operation.

Solution to the problem that the controller is normal but there is no display on the display:

Make sure the LED display is powered on normally. Check whether the connection between the HUB distribution board and the display screen is reversed. Check whether the edited and sent program is empty.

How to deal with the problem that the whole screen is not bright or dimly lit on the unit board:

Check the power connection cable, the 26P cable between the unit boards and the power module indicator light. Use a multimeter to measure the unit board voltage to see if it is normal, and check the power module output voltage. If the voltage of the power module is low, adjust and fine-tune the voltage to reach the standard.

Possible reasons and solutions for black screen on LED display:

Make sure all hardware is powered on correctly. Check whether the serial port cable is loose or fallen off. Confirm whether the HUB distribution board and the display screen are tightly connected and whether they are plugged in backwards. The above solutions are for reference only, and the specific situation may vary depending on the LED screen model and brand. When dealing with faults, it is recommended to contact the LED display manufacturer or technical support for more detailed help.
