For outdoor LED display, damage caused by wind, rain, lightning, electricity and other natural factors are not covered by warranty. The owner needs to insure to the insurance company, and the insurance company will pay for the damage. Maintenance service period, general failure within 8 hours to solve maintenance problems, major accidents no more than 24 hours. Repair to replace the module and other accessories, no more than 24 hours. After the completion of maintenance, One service to ensure that the large screen does not appear above the module level (such as module color deviation, module black, a column does not light, etc.) of the fault, normal playback. Clean up for the lower protection level of the display, especially outdoor screen, there is dust in the atmosphere from the ventilation holes into the equipment, for fans and other equipment will accelerate wear and tear or even damage. Dust will also fall on the surface of the control device inside the display, reducing thermal conductivity and insulation, when the humid weather dust absorbs moisture in the air leading to short circuit; long-term can also lead to PCB boards and electronic components of the mold, resulting in a decline in the technical performance of the equipment, failure.
So, the LED display cleanup work seems simple, in fact, is a very important part of the maintenance work. Fastening LED display belongs to the high power consumption equipment, running for quite some time, due to the many starts and stops and operation, which power supply part of the terminals due to hot and cold will cause loose, contact is not firm, the formation of false connection, serious heat, and even ignited next to the plastic components. Signal terminals will also be due to the ambient temperature hot and cold changes in loosening, moisture erosion resulting in poor contact, and subsequently lead to equipment failure, so it is necessary to LED display connectors for regular fastening. In the fastener adjustment, should force evenly and appropriately, to ensure solid and effective. Display surface cleaning in the bright screen and black screen two states of the LED display for visual inspection, check. Including: whether the display surface is contaminated, the purpose is to remove the surface dirt on the luminous characteristics of the impact; display surface with or without damage cracks; communication distribution cable line is normal.
