how to deal with it LED large screen’s problem.

Nowadays, LED screen is more and more used, so if LED screen is abnormal, how do you deal with them? Általában véve, according to the feedback from previous customers, the full-color LED display has the following standards and maintenance methods:

1. The whole interface is not a sporadic light spot, also known as small black spot, bad light spot and dead light spot. (if there is no field, if the failure rate is within the scope, the display will not be affected), the whole screen will be colorful.

2. LED indoor full-color screen has output power jump box, the actual operation is repeated as well. (when the supply line of short-circuit inspection is very positive, the terminal of negative switching power cable is to see whether there is the next touch, as well as the power supply master switch; one is to lower the wire mesh of the object)

3. LED display screen a row of abnormal results show that a flash of miscellaneous points. (from the beginning of the board in the abnormal important parts, check whether the line row is loose and whether the interface technology of the board and wire row is damaged. If there is any problem, the line bank or the common fault board must be replaced.)

4. The LED display screen does not display large, black. (considering the problem of transmission of the first driving force, the power supply master switch looks up to see whether the power is released or not. If the cable is loosened and the signal is not pushed in the past, there is a problem in accepting the damaged memory card; clearing one can find a solution)

5. When the LED display screen plays video or pictures, the system on the computer can show that the economic development of different regions is normal, but sometimes the screen is jammed and crashes. (generally, it is difficult to control the quality of network cable. The packet loss caused by the whole process of technical transmission of video information content and data information results in the crash of the screen. The replacement of the network cable with better working quality can be processed.)

6. A LED board on the display screen shows a flashing square, miscellaneous spot, and a number of lights in parallel display are abnormal. That’s the board problem. It’s OK to replace the board with abnormal display. The installation of screen wall in the room is generally magnet suction, and the board can be replaced with a little force.)

(generally, the push card is not good, please replace the push card and solve the problem)

9. The software dialog box of LED display screen shows that everything is normal, but the interface on the screen is disordered, displayed separately or divided into several dialog boxes to independently study and display the same interface. (it’s a problem in the system software setting. If you go to China, you can choose the appropriate settings according to the settings.)

10. It should be displayed on the desktop LED display screen. (if the LED is not equipped with a video processor, this feature will not be implemented; if it is equipped with a video processor, the adjustment can be carried out in the video processor, and the screen area will display the same step to the led to display the Mai Pu style color.)

LED display screen as the most important contemporary research display equipment, we not only need to understand its strong role, but also must be grasped by students. It is all about the basic maintenance management scheme of LED display screen.
