In the process of use, the outdoor LED display caused harm to a variety of reasons, the need for waterproof, dustproof, heat dissipation, corrosion, static electricity, lightning, small animals, and regularly do maintenance and overhaul. Generally speaking, outdoor LED display way maintenance is mainly “cleaning, fastening, appearance check, correction” several kinds.

Outdoor LED display clean box internal cleaning for the lower protection level display, especially outdoor screen, the atmosphere has dust from the ventilation holes into the equipment, for the fan and other equipment will accelerate wear and tear or even damage, dust will also fall on the display internal control device surface, reduce thermal conductivity and insulation properties, when the dust absorbs moisture in the air leading to a short circuit in humid weather, long-term can also lead to the PCB and electronic components of mold, resulting in the mold of the electronic components, resulting in the PCB board. Electronic components of the mold, resulting in a decline in the technical performance of the equipment, failure, so the display equipment cleaning work seems simple, in fact, is a very important way of maintenance work. When cleaning the dust inside the display, remember to disconnect the power supply, careful operation.

Screen surface cleaning LED electronic display after a long time to clean the screen surface accumulation of dust and impurities. The first thing to consider is to buy a better quality cleaning kit, the cost of cleaning fluid generally include electrolyte, high purity distilled water, anti-static liquid, etc., can effectively clean the LED screen dust and other dirt marks. Some people think that clear water can also be, and will not affect the outdoor LED display. However, the cleaning effect of water is relatively poor, and after cleaning the dust will attach again. One thing to note at the same time is that water should never be sprayed on the screen, but a small amount of cleaning solution should be sprayed on the cleaning cloth, and then gently wipe in the same direction, and before cleaning, you need to pull out the power cord. Finally, use a vacuum cleaner to suck up the water droplets and water marks left after wet washing to ensure that the display mask is neat and dust-free.

Outdoor LED display fastening large-scale LED display belongs to the high power consumption equipment, running for quite some time, due to the many start-stop and run, which power supply part of the terminals due to hot and cold will cause loosening, contact is not firm, will be false, serious when the heat will ignite the plastic components next to the signal terminals will be due to the ambient temperature hot and cold changes in the loosening of moisture erosion leads to poor contact, and then lead to equipment failure, therefore, must often check and find a way to ensure that the display mask neat and dusty. Equipment failure, so we must always check the fastening degree of the connectors in the equipment. In the fastener adjustment, should force evenly and appropriately, to ensure solid and effective.

The appearance of outdoor LED display screen inspection refers to the appearance of the display screen equipment to do visual or measurement observation, inspection. Including equipment to the outer surface of the damage cracks. Communication distribution cable line is normal. For high protection level equipment, although the selection of high-reliability components and connectors, but lead to its airtightness becomes a key factor, so it is more important to regularly check the sealing at the integrity of the steel structure of the outdoor screen to check the surface paint and corrosion. At the same time also need to regularly overhaul the display of heat dissipation and lightning protection equipment.

Outdoor LED display correction LED display of the theoretical life of 100,000 hours, but in fact, a display in the operation of about 5,000 to 10,000 hours after the uniformity will deteriorate, began to flower, the commercial value of the reduction, at this time we must consider the point by point correction.

LED display correction before the preparatory work to be done:

1, clean the LED display, remove the dust and stains on the light surface and mask to avoid the impact on the brightness. If you need to replace the mask, please ensure that the mask color is consistent with the previous, otherwise the display will be affected, especially in the daytime, after correction is not much improvement.

2、 Replace the modules that are not functioning properly: some of the lamps are not bright, more dead lamps, scanning is not normal, the overall lamps are too dark (resistance may be incorrect), wiring or jack problems affecting the display, and so on. Ensure that the final display, scanning, the screen is normal, no dark, often bright, bright and other phenomena before;.

3, the receiver card upgrade: If the current receiver card does not support calibration or bandwidth points are not enough, you need to upgrade. Because of the risk of dead card upgrade, customers need to contact the control system company in advance for upgrading and related processing.

Finally, large-scale display in the operation of the operator should also pay attention to the inspection, observe whether there is a strange sound, odor, light and other phenomena, such as the display is not used for a long time, and then put into use to inspect beforehand. It is worth noting that the table sticker LED display unused for a long time will lead to a decline in reliability, it is recommended that the weekly use of more than 1 hour, to reduce the erosion of moisture on the display.

LED display proper operation also includes in the use of playing the right program, for example: due to the light decay characteristics of the LED lamp itself, long-term play the same picture lead to local light decay; There is a long time to play a higher brightness program will lead to a variety of components work at full capacity, accelerated aging; At the same time, from an economic point of view, it will also consume a lot of electricity, operating costs increase, so in the use of each of you! Therefore, we should pay attention to it in use.
