Melton: led display repair with how to clean up? In the course because of pollution, loose, vibration, heat, temperature changes and other factors cause a variety of failures, affecting the normal use of led display, even cause serious accidents. Therefore, led display for regular maintenance is essential. Then led display routine maintenance mainly do? Here's to you announced one by one.
First, we must patrol
    General led display inspection are based on the "Moon Patrol" system, perform maintenance led display a large "Week inspection system", the specific content and speed of response maintenance commitment:
   1, led display screen body repair, including lamps, modules, modules, power supplies, control cards;
   2, led display control system maintenance, including controllers, fiber optic converter card, distributor, send cards;
   3, led display dedicated playback operation software, including playback software maintenance, upgrades;
   4, on a regular basis (once a month degrees) technical personnel on-site inspection, inspection and  maintenance of the system;
   5. escort major events: the company technical staff to ensure the smooth conduct on-site guidance activities.
   6, for outdoor LED display, damage due to wind, rain, thunder, electricity and other natural factors, is not covered by the warranty. Require owners to insurance companies, the insurance company paid.
   7, during the maintenance service, to solve maintenance problems within the general failure eight hours, a major accident is not more than 24 hours. Maintenance To replace modules and other accessories, no more than 24 hours. After the repair is completed, One service does not appear to ensure a large screen above the module level (eg modules cast, black module, a column does not light, etc.) failure, normal playback.
   Second, clean up A lower level of protection for the display, especially outdoor screen, atmospheric dust from the air vents into the device, for the fans and other equipment will accelerate wear or damage. Dust will fall on the internal display control device surface, reducing thermal and insulating properties, the case of wet weather dirt absorb moisture in the air cause a short circuit; long may also lead to mildew PCB board and electronic components, resulting in equipment technical performance, error occured. Therefore, led display cleanup seemingly simple, in fact, maintenance work in a very important aspect.
    Third, fastening led display belong drain devices, running for quite some time, due to multiple start and stop operation, in which the power supply part of the terminals due to cold can cause loose, strong, form virtual access, and in severe heat, even ignite plastic components beside it. Signal terminals will loosen due to environmental temperature changes of hot and cold, moisture erosion resulting in poor contact, then led to equipment failure, it is necessary for connection led display periodically tightened. When the fastener adjustment, should force uniform appropriate to ensure robust and effective.
    Fourth, the display surface cleaning In the bright screen and black two states led display visually checked. Including: whether the display surface is contaminated, the purpose is to remove the influence of surface dirt on the light-emitting properties; the display surface without injury cracks; telecommunications cable distribution line is normal; for the high level of protection of the equipment, although due to the selection of high reliability The components and connectors, but lead to tightness become the key factor, therefore, to regularly check the seals intact; steel for outdoor screen to check the surface paint and rust circumstances; for outdoor screen surface contamination is particularly serious, but also on the display surface cleaning.
    Cleaning the case led display high-altitude operations, to be equipped with professional cleaning team. Cleaning operations using aerial sling way (commonly known as Spider-Man) or the use of hanging blue, configuration professional cleaning equipment, cleaning personnel depending on dirt on the screen to select a different cleaning agents targeted cleaning, thereby ensuring that no damage LED lamp complete cleaning work led display and mask under the premise.
  Cleaning ready to note two things:
  First, before cleaning, we need to pull out the power cord.
  Second, the choice of cleaning fluid, cleaning fluids generally includes an electrolyte, a high purity distilled water, anti-static fluid, etc., to choose a good quality to effectively dust and other dirt on the clean imprint LED screen.
   Cleaning and maintenance is divided into three steps:
     The first step: vacuuming. First sucked, remove dirt and dust mask display surface.
     Step two: wet cleaning. Be careful not to put lotion directly onto the screen, but you want a little cleaning solution sprayed onto the cleaning cloth, and then gently wipe down the same direction. You can also use a soft brush on a vacuum cleaner to scrub the lamp mask, brushing the dirt clean.
    The third step: drying. The use of wet and dry vacuum cleaner water marks left washed, ensure that the display mask clean and free of dust.
