Today LED electronic display has become a part of people's lives, streets, square station, you can see all kinds of different shapes and sizes of LED electronic display. It is a set of optical, structural mechanics, electronics, computer science in one of the systems engineering. According to statistics, all domestic LED electronic display of 90 percent have large or small fault, for which we summed up the main reasons for these failures, I believe that with these, we can control the source from the source , Improve the quality of the display.
The main factors that cause LED electronic display failure: AC power distribution wiring harness, terminal, connector, signal and low voltage DC connection harness and connector, switching power supply module, fan, plastic shell components. These interfaces, cables, power supply, bottom shell if not selected, will lead to LED electronic display overall or local black, Huaping, mosaic, no signal. These are also very difficult to maintain the problem, so we are in the production process is to pay attention to reduce the failure rate.
The rest of the fault is caused by the following factors: PCBA on the solder joints, capacitors, terminals, LED lights, box protection level caused by leakage of dust accumulation, leakage screw hardware hardware corrosion, control board.
These causes the LED electronic display with a blind or highlighted, one or more lines do not light, lack of color, etc. If the control card or software problems will lead to the image display is not normal. Outdoor LED electronic display must be strictly in accordance with the testing standards to design, waterproof and dustproof, anti-wind high temperature, or prone to a variety of failures, and even make the entire LED electronic display scrapped.
In addition, the operation of the display staff should have the basic knowledge, with good habits, coupled with professional maintenance personnel, but also to a certain extent, reduce the failure rate.
