How to Solve the Fault of LED Display Screen

How to solve the flower screen fault of LED display? There are many reasons why the flower screen of full-color LED display can not be displayed normally. Here is a summary of how to solve the flower screen of full-color LED display.If the new screen is powered on, it may be that the control card settings are not scanned correctly, or the cable is not inserted correctly (check the cable from the control card to the first board). This problem will also occur if the 5V power supply is connected incorrectly.If this phenomenon is suddenly found after using for a period of time, in addition to the failure of the control card, the biggest possibility is that the board is flooded and burns the chip or power supply.

How to Solve the Fault of LED Display Screen 1

Also, you can try a display connected to a DVI interface. First, check whether the DVI output port of the graphics card has a normal signal. The DVI interface resolution of general lingxingyu card is 1024 * 768. The reason for the LED display screen may also be the problem of the graphics card or the driver. Try to unplug the network cable of the receiving card behind the display screen and press the debugging button on the receiving card to see whether the screen body scanning is normal.In addition, other reasons for the flower screen of full-color LED display are also provided for your reference:1. LED display flower screen cannot be displayed

Solution: check whether the power supply of the electronic display screen is normal and whether there is 220V strong current input2. The display of LED electronic display screen is abnormal, and the flower screenresolvent:

(1) Whether the parameter setting of LED control card is correct and whether there is signal transmitted to the LED control card of electronic display screen;(2) Check whether the communication line communicates normally and whether the LED control card has signal input;(3) Whether the 5V power supply of LED control card is normal;

3. Part of the screen body of the electronic display screen is abnormal, such as black screen and flower screenSolution: check whether the screen power supply with abnormal display works normally; Signal transmission line fault; Single module failure of screen body.A. There is a problem with the output

How to Solve the Fault of LED Display Screen 2

1. Check whether the line from the output interface to the signal output IC is connected or short circuited.2. Check whether the clock latch signal of the output port is normal.3. Check whether the cascade output data port between the last drive IC is connected with the data port of the output interface or short circuited.

4. Poor heat dissipation of the chassis leads to the rise of the temperature of the graphics card.Solution: eliminate the heat dissipation problem.Check whether the fan operates normally, add oil to the fan, clean the dust in the chassis, and eliminate the fault after solving the heat dissipation problem.

5. Reinstallation of the system, graphics card or display does not support high resolution.resolvent:(1) Restart the computer, press F8 continuously, in the Advanced Startup menu, select "safe mode" and enter to log in to the system, then enter the display setting under windows, select the 16 color status, click the "apply" button and click the "OK" button.

(2) Restart the computer. In the normal mode of windows, enter the device manager, delete the graphics card driver, and restart the computer.

Let's Introduce Several Tips for Energy Saving of LED Display Screen in Detail
With the rapid development of society, "energy saving" has become one of the topics that people pay more and more attention to, and the LED industry is no exception. The survey found that led energy-saving products are widely welcomed by the public, such as LED energy-saving lamps, and LED displays belonging to the LED industry should also keep pace with the times, respond to the national call and promote energy-saving and environmental protection products. As we all know, LED display may not achieve the ideal effect in energy saving because of its high brightness, but this does not mean that it must be a high energy consumption product. So how can led display achieve energy saving? Maipu Guangcai LED display manufacturer introduces in detail several tips for energy saving of LED display, and hopes to adopt them.1. The LED display screen made of environmental protection materials can achieve the purpose of waterproof, dustproof and ultraviolet radiation without glue filling after special processing technology. It has less consumables than the products produced by general process and is more environmentally friendly.2. The brightness adjustment device is designed. The brightness of the application occasion is different under different weather conditions. In order to make the LED display screen achieve the best display effect, which is neither bright nor dark, the LED display screen is specially designed with a brightness 256 level adjustment device and the function of automatically adjusting the brightness according to the surrounding environment, It can ensure that the LED display screen can present a good display effect for the audience under various external brightness environments.3. Constant current noise reduction technology, the LED display driver chip adopts the international advanced LED display special chip system, which is a leading manufacturer in the field of full-color LED display. Combined with the characteristics of the chip, the constant current noise reduction technology is studied and formed to ensure that the influence of other noise source factors such as power supply on LED electronic display screen is reduced to a very low level. Some drive ICs can also save the original 5V voltage to 4.2V to achieve the function of energy saving.4. The strong convection heat removal system makes the heat dissipation system stable. Maipu Guangcai LED display screen will release more heat after working for a long time. If the heat is not released in time, it will cause a certain degree of damage to the screen body and affect the normal use of the screen. In order to ensure the normal operation of the display screen in a stable environment, it is necessary to strengthen the heat dissipation system of the LED display screen.5. Power supply, the realization of LED energy-saving display screen mainly starts from the power supply. The existing LED display screen directly adopts half bridge or full bridge high-efficiency switching power supply, coupled with synchronous rectification, with remarkable energy-saving effect. Reduce the power supply voltage as much as possible under the condition of constant current to the driving IC, and achieve better energy-saving effect by supplying power separately through each tube core of red, green and blue.If the selection of LED display screen can start from five aspects: material selection, brightness adjustment, noise reduction treatment, heat dissipation improvement and power supply, then led display screen can also make its own efforts for energy conservation and environmental protection.fqj
