LED显示屏花屏故障怎么解决呢?

LED display screen how to solve the problem?

LED全彩显示屏花屏无法正常显示有多种原因，下面小编给大家总结一下具体的解决办法。

There are many reasons why the LED full-color display screen cannot display normally. Here is a summary of specific solutions.

一、如果LED全彩显示屏刚装上通电就出现花屏现象，那可能是控制卡设置扫描不对，或排线没有插对(检查从控制卡到第一个板子的排线)，5V电源接错也会出现这个问题。

1. If the LED full-color display panel has a screen sprouting as soon as it is installed with power, it may be that the scanning of the control card is wrong, or the line is not inserted correctly (check the line from the control card to the first board), this problem may also occur when the 5V power connection is wrong.

二、如果LED全彩显示屏使用一段时间后突然发现花屏，那除了控制卡故障外，最大的可能就是板子进水烧了芯片或电源。

2. If the LED full-color display panel is used for a period of time and the screen is blown suddenly, the biggest possibility is that the chip or power source is burnt by the water in the panel except the control card failure.

还有可以试试接个DVI接口的显示器先，看下显卡的DVI输出口是否信号正常。

You can also try a DVI interface monitor first, to see if the video card DVI output signal normal.

一般灵星雨的卡， DVI接口分辨率是1024*768的。

General ling star rain card, DVI interface resolution is 1024*768.

导致LED显示屏花屏的原因，还可能是显卡的问题，或者驱动问题。

LED display screen can also be caused by graphics card problems, or driving problems.

试着把LED显示屏后面的接收卡的网线拔掉按接收卡上的调试按钮，看屏体扫描是否正常。

Try to unplug the network cable of the receiving card behind the LED display and press the debugging button on the receiving card to see if the screen body scan is normal.

三、引起LED全彩显示屏花屏的其他原因，可能是以下几个方面引起的：

3. Other causes for LED full-color display screen display may be caused by the following aspects:

1、查看电子显示屏供电是否正常，是否有220V强电输入。

1. Check whether the power supply of electronic display screen is normal, and whether there is 220V strong power input.

2、LED控制卡参数设置是否正确，有没有信号传输到电子显示屏LED控制卡上;

2. Whether the parameters of the LED control card are set correctly, and whether the signal is transmitted to the LED control card of the electronic display screen;

通讯线是否通讯正常，查看LED控制卡是否有信号输入;

Whether the communication line is normal, check whether the LED control card has signal input;

LED控制卡5V供电是否正常。

LED control card 5V power supply is normal.

3、查看显示异常的屏体电源是否正常工作;

3. Check whether the abnormal screen power supply is working normally;

信号传输线故障;

Fault of signal transmission line;

屏体单个模组故障。

Single module failure of screen.

（1）、检测输出接口到信号输出IC的线路是否连接或短路。

(1) check whether the line from the output interface to the signal output IC is connected or short-circuited.

（2）、检测输出口的时钟锁存信号是否正常。

(2) check whether the clock latch signal of the output port is normal.

（3）、检测最后一个驱动IC之间的级连输出数据口是否与输出接口的数据口连接或是否短路。

(3) check whether the level connecting output data port between the last drive IC is connected with the output data port or short circuit.

4、机箱散热不好，导致显卡温度升高所致。

4. The case has poor heat dissipation, which results in the temperature rise of the graphics card.

检查风扇运转是否正常，给风扇加油，清理机箱内的灰尘，解决散热问题后故障即可排除。

Check whether the fan is running normally, oil the fan, clean the dust in the box, and remove the trouble after heat dissipation.

5、重装系统，显卡或者显示器不支持高分辨率所致。

5. Reinstall the system, and the graphics card or monitor does not support high resolution.

可以通过以下两个办法解决。

There are two ways to do this.

(1)、重启电脑，连续按F8键，在高级启动菜单，选择进入“安全模式”回车登陆系统，然后在windows下进入显示设置，选择16色状态后，点击“应用”按钮，点击“确定”按钮。

(1) restart the computer, press the F8 key continuously, in the advanced start menu, select enter into "safe mode" to log in the system, and then enter the display setting under Windows. After selecting 16 colors, click "apply" button and click "ok" button.

(2)、重新启动电脑，在windows正常模式下，进入设备管理器，删除显卡驱动程序，重新启动电脑即可。

(2) restart the computer. In normal Windows mode, enter the device manager, delete the video card driver and restart the computer.
