led display maintenance work

For LED display screens with low protection levels, especially outdoor screens, dust in the air enters the equipment through the vents, and equipment such as cooling fans will accelerate wear and even destroy. Dust will continue to fall on the surface of the control components inside the LED display screen, reducing heat transfer and insulation performance. When wet weather, the dust absorbs moisture in the air and causes short-circuit failure; long-term can also cause moldy PCB boards and electronic components. Causes the technical characteristics of the equipment to decrease, causing problems. Therefore, the cleaning of the led display looks simple, but in fact it is a very important stage in the maintenance work.

LED display screen belongs to high power consumption equipment. After operating for a period of time, due to several times of start-stop and operation, some of the wiring terminals of the power supply system will be loose due to heat and cold, and the touch is not firm, resulting in virtual connection, which is more serious It will be hot when Therefore, be sure to tighten the connecting parts of the led display screen on time. When adjusting the standard parts, they should be well-balanced to ensure firmness and reasonableness.
