LED display screen failure how to solve it? Full-color LED display screen can not be displayed properly for a variety of reasons, here is a summary of the full-color LED display screen how to solve the problem.

If the new screen is installed on the power on the flower, it may be the control card set scanning is not right, or the wires are not inserted correctly (check the wires from the control card to the first board), 5V power supply connected to the wrong will also appear this problem.

If the use of a period of time after the sudden discovery of this phenomenon, then in addition to the control card failure, the biggest possibility is that the board into the water burned chip or power supply.

You can also try to connect a DVI interface monitor first, see if the DVI output port of the graphics card signal is normal. General Lingxingyu card, then DVI interface resolution is 1024 * 768. LED display screen causes, may also be the problem of the graphics card, or driver problems. Try to unplug the network cable of the receiver card behind the display and press the debug button on the receiver card to see if the screen scanning is normal.

In addition, caused by full-color LED display screen other reasons, also provides you with reference:

1, LED display screen can not display

Solution: check whether the electronic display power supply is normal, whether there is 220V strong power input

2, LED electronic display screen display is not normal, splash screen

Solution:

(1) LED control card parameters are set correctly, there is no signal transmission to the electronic display LED control card;

(2) communication line whether communication is normal, check whether the LED control card signal input;

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

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

Solution: Check whether the power supply of the screen display abnormalities work properly; signal transmission line failure; screen individual module failure.

Output problems

1, test the output interface to the signal output IC line is connected or short-circuited.

2、Detect whether the clock latch signal of the output port is normal.

3, detect the last driver IC between the cascade output data port is connected to the data port of the output interface or short-circuit.

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

Solution:Exclude heat dissipation problems.

Check whether the fan is running normally, add oil to the fan, clean up the dust in the chassis, solve the cooling problem can be eliminated after the failure.

5, reinstallation of the system, the graphics card or monitor does not support high resolution.

Solution:

(1) restart the computer, continuously press the F8 key, in the advanced boot menu, select the “safe mode” enter the login system, and then enter the display settings in windows, select the 16-color state, click the “Apply” button, click the “OK” button. Click “OK” button.

(2) Reboot your computer, in windows normal mode, enter the device manager, delete the graphics card driver, restart your computer.
