If you suddenly find this phenomenon after using it for a while, in addition to the control card failure, the biggest possibility is that the board is flooded with water or a power supply.

Also try to connect the display of a DVI interface first, see if the DVI output port of the graphics card is normal. In the case of a general meteor shower card, the resolution of the DVI interface is 1024*768. The cause of the LED display screen may also be a problem with the graphics card, or a driver problem. Try to unplug the network cable of the receiving card behind the display and press the debug button on the receiving card to see if the screen scan is normal.

In addition, other reasons that cause the full-color LED display screen are also provided for your reference:

1, LED display screen can not be displayed

Solution: Check if the power supply of the electronic display is normal, and if there is a 220V power input.

2, LED electronic display is not normal, flower screen

Solution:

(1) Whether the LED control card parameter setting is correct, and whether there is any signal transmitted to the electronic display LED control card;

(2) Whether the communication line is communicating normally, check whether the LED control card has signal input;

(3) Whether the 5V power supply of the LED control card is normal;

3, the electronic display part of the screen display is not normal, such as black screen, flower screen

Solution: Check whether the screen power supply showing abnormality is working normally; the signal transmission line is faulty; the single module of the screen body is faulty.

A. There is a problem with the output.

1. Check whether the line from the output interface to the signal output IC is connected or shorted.

2. Check if the clock latch signal of the output port is normal.

3. Check if the cascaded output data port between the last driver IC is connected to the data port of the output interface or is shorted.

4, the chassis heat is not good, resulting in increased graphics card temperature.

Solution: Eliminate heat dissipation problems.

Check whether the fan is running normally, refuel the fan, clean the dust inside the chassis, and solve the heat dissipation problem.

5, reinstall the system, graphics card or display does not support high resolution.

Solution:

(1) Restart the computer, press F8 continuously, in the advanced startup menu, choose to enter “Safe Mode” and press Enter to log in to the system, then enter the display settings under Windows. After selecting the 16-color status, click the “Apply” button and click “OK”. " button.
