You know how much LED display maintenance content?

LED display in the use of the process because of pollution, loosening, vibration, heat, environmental factors such as temperature changes caused by various faults, affecting the normal use of LED electronic display, and even cause serious accidents. Therefore, do regular maintenance on the LED display, which can the LED display in the best running state, and can effectively prevent the occurrence of the fault, the normal operation of the LED display to get twice the result with half the effort. The following is a small series of reference to an enterprise maintenance content, to share with you.

from the "LED display regular maintenance form" can be seen, LED display maintenance mode has four main aspects: inspection, cleaning, fastening, and the display screen surface cleaning. A LED display and the inspection inspection cycle generally use the "monthly inspection system", large LED display maintenance execution "weekly inspection system" LED "will display weekly monthly maintenance inspection table", its contents are as follows:


specific maintenance content and response speed of commitment: 1, the LED display screen, including maintenance, lamp module, module the power supply control card; 2, LED display control system maintenance, including controller, optical conversion card, distributor, sending card; 3, special LED display playback software, including maintenance, playback software upgrade; 4, regular (monthly time) on-site inspection and technical personnel, inspection and maintenance of the system; 5 major activities: Escort company technical staff guidance to ensure the on-site activities carried out smoothly. 6, for the outdoor LED display, due to wind, rain, thunder, electricity and other natural factors, the damage is not within the scope of the warranty. Require the owner to the insurance company, the insurance company paid by the insurance company. During 7, maintenance service, general failure within 8 hours to solve the maintenance problems of major accidents, no more than 24 hours. Repair to replace parts of the module, no more than 24 hours. After the completion of maintenance, one service to ensure that the big screen does not appear above the module level (such as module partial color, black module, a column is not bright, etc.), the normal play. Second, clean up for the lower grade of the door screen, especially outdoor screen, atmospheric dust from the ventilation holes into the device, for fan equipment will accelerate the wear and tear and damage. The dust will fall within the display control device surface and lower thermal conductivity and electrical insulation properties. In case of wet weather dust absorption of moisture in the air, causing a short; long term can also lead to PCB and electronic element of mildew, resulting in equipment, technical performance decreased failure. Therefore, the LED display is simple to clean up the work, in fact, is a very important part of the maintenance of maintenance work. Third, fastening LED display belongs to the high power consumption equipment, running for quite a long time, due to repeated start stop and run, which part of the power supply terminal due to hot and cold will cause the loose contact with prison, formed virtual connection, serious may have a fever, even ignited next to the plastic element. Signal terminals will also be due to changes in the temperature and temperature changes in the environment, moisture erosion resulting in poor contact, resulting in equipment failure, and therefore must be on the LED display connection parts for a regular tightening. When the fastener is adjusted, it should be uniform and appropriate to ensure that it is robust and effective. Four, the screen surface cleaning in the bright screen and black two conditions on the LED display, visual inspection. Including: display surface is contaminated. The purpose is to remove dirt on the surfaces of the effect on the luminescence properties; the display surface without damage cracks; power distribution communication cable line is normal; equipment for the high degree of protection, although due to the use of the high reliability of the components and connector, but lead to sealed becomes the key factor. Therefore, it is necessary to regularly check sealing place in good condition; for steel structure for outdoor screen to check the surface paint and corrosion; the room outer surface pollution is particularly serious, but also on the display surface cleaning. LED display cleaning is a high-altitude operation, need to be equipped with professional cleaning team. Cleaning the aerial rope way (commonly known as spider man), or the blue crane, configuration of professional cleaning equipment, cleaning personnel according to screen different dirt choose different cleaning agent for cleaning, so as to ensure complete LED display screen cleaning work under the condition of not damaging LED tube and mask. Cleaning preparation need to pay attention to two points: first, before cleaning, need to pull out the power cord. Two, the choice of cleaning liquid, cleaning liquid generally include the electrolyte, high purity distilled water, anti-static liquid, etc., to choose good quality, in order to effectively clean the dust and other dirt on the screen LED screen. Cleaning and maintenance is divided into three steps: the first step: dust. Remove dirt and dust from the surface of the screen. Second step: wet wash. Note that the lotion can not be sprayed directly on the screen, but a little clean liquid sprayed on a clean cloth, and then gently wipe the same direction. The lamp can also mask scrub with a soft brush cleaner, dirt cleaning. The third step: drying. The use of wet wash after leaving a vacuum cleaner sucking up water marks, ensure the screen clean and free of dust mask.
