　　How to do daily maintenance of led display

　　LED display screen will cause various faults due to pollution, looseness, vibration, heating, environmental temperature changes and other factors in the use process, affecting the normal use of LED display screen, and even causing serious accidents. Therefore, regular maintenance of led display is essential. So what is the main purpose of daily maintenance of led display?

　　1、 Patrol inspection

　　Generally, the "monthly inspection system" is adopted for the inspection of LED display, and the "weekly inspection system" is adopted for the maintenance of large LED display.

　　2、 Cleaning

　　For the display screen with low protection level, especially the outdoor screen, there is dust in the atmosphere entering the equipment through the ventilation hole, and the fan and other equipment will be quickly worn or even damaged. The dust will also fall on the surface of the internal control device of the display screen, reducing the thermal conductivity and insulation performance. In wet weather, the dust absorbs moisture in the air, causing a short circuit; It can also lead to mildew of PCB board and electronic components for a long time, resulting in decline of technical performance of equipment and failure. Therefore, the cleaning of led display screen seems simple, but it is actually a very important part of the maintenance work.

　　3、 Fastening

　　LED display is a high power consumption device. After a long period of operation, due to multiple startup, shutdown and operation, the wiring terminals of the power supply part will become loose due to cold and hot, and the contact is not firm, forming a virtual connection. In serious cases, it will heat up, and even ignite the plastic components beside it. The signal wiring terminal will also become loose due to the cold and hot changes in the ambient temperature, and the moisture erosion will lead to poor contact, which will lead to equipment failure. Therefore, the connectors of the led display must be fastened regularly. When adjusting fasteners, the force shall be uniform and appropriate to ensure firm and effective.
