Dust may also fall on the surface of display internal control device, reduce the thermal conductivity and insulation performance, in wet weather when dust absorbing moisture in the air will lead to short circuit;
Long-term can also lead to PCB and electronic components of mildew, the equipment technical performance, fault occurs.
Therefore, display the cleanup looks be like simple, but in fact is an important step in the maintenance work.
Three, regular display screen fittings of fastening work belongs to high power consumption equipment of LED display screen, when running after a period of time, due to stop and run for many times, including the terminal of the power supply part due to the hot and cold can cause looseness, contact not firm, form virtual connect, serious when fever, even raising beside the plastic components.
Signal terminals will be due to the environmental change of temperature cold heat is loose, high lead to poor contact, then result in equipment failure, so must be carried out on the fittings of LED display fastening on a regular basis.
In fasteners, during adjustment should be forcibly even properly and ensure solid and effective.
