LED display screen will cause various failures due to pollution, looseness, vibration, heat, environmental temperature and other factors during use, which will affect the normal use of LED display screens and even cause serious accidents. Therefore, regular maintenance of LED display screens is essential. So what do you do with daily maintenance of LED display? Below Novi Xin photoelectric to come to you one by one announced.
First of all, to inspect
What do you know about LED display maintenance? General LED display inspections are using "monthly inspection system", large LED display maintenance are implemented "week inspection system," specific maintenance content and response speed commitment:
1, LED display screen body maintenance, including lamp, module, module, power supply, control card;
2, LED display control system maintenance, including the controller, optical fiber conversion card, distributor, send card;
3, LED display special playback operating software, including playback software maintenance, upgrades;
4, regular (monthly) technical staff on-site inspection, inspection and maintenance of the system;
5. The major activities are guaranteed: The company's technical staff guides to ensure the smooth development of on-site activities.
6, for outdoor LED display, due to wind, rain, lightning, electricity and other natural factors caused by the damage, not within the scope of the warranty. The owner is required to insure the insurance company and is paid by the insurance company.
7, maintenance services, the general failure within 8 hours to solve maintenance problems, major accidents do not exceed 24 hours. Maintenance to replace modules and other accessories, no more than 24 hours. After the maintenance is completed, the 壹 service ensures that the large screen does not appear faulty at the module level (such as the color cast of the module, the module black, and the blackout of one column) and plays normally.
Second, clean up
For screens with a low degree of protection, especially outdoor screens, dust in the atmosphere enters the device through the ventilation holes, which can accelerate wear and even damage the fans and other devices. Dust will also fall on the surface of the display device to control the device, reducing heat conduction and insulation performance. In wet weather, dust absorbs moisture in the air and causes short circuit. In the long term, it can also lead to mildew in PCB boards and electronic components, resulting in a decline in the technical performance of the equipment. error occured. Therefore, the cleanup of LED display screens seems simple, and it is actually a very important part of the maintenance work.
Third, fastening
The LED display is a high-power-consumption device. After a certain period of operation, due to multiple start-stops and operations, the terminals of the power supply part are loosened due to cold and heat, the contact is not solid, the virtual connection is formed, and the heat is severe when it is severe. Ignit the plastic element next to it. The signal terminals are also loosened due to the change of the ambient temperature, hot and cold, and the moisture erosion causes poor contact, which in turn leads to equipment failure. Therefore, the connector of the LED display screen must be tightened regularly. When adjusting the fasteners, the force should be applied evenly and properly to ensure solid and effective.
Fourth, the display surface clean
The LED display is visually inspected and checked under both light and black screen conditions. Including: whether the display surface is contaminated, the purpose is to remove the effect of surface dirt on the light emitting characteristics; whether the display surface has damage cracks; communication distribution cable lines are normal; for the equipment of high protection level, although due to the high reliability The components and connectors, but resulting in hermeticity has become a key factor, therefore, to regularly check the integrity of the seal; for outdoor screen steel structure to check the surface paint and rust; for the outdoor screen surface is particularly serious pollution, but also Clean the display surface.
LED display cleaning is a high-altitude operation and requires a professional cleaning team. The cleaning operation adopts a high-altitude hanging rope method (commonly known as spider man) or hanging blue, and professional cleaning equipment is configured. The cleaning personnel selects different cleaning agents according to different dirt on the screen to perform targeted cleaning, thereby ensuring that the LED tubes are not damaged. And under the premise of the mask to complete the LED display cleaning. There are two things to note when cleaning: 1. Before cleaning, you need to pull out the power cord. Second, the choice of cleaning fluid, cleaning fluid generally includes electrolyte, high-purity distilled water, antistatic fluid, etc., to choose a good quality, in order to effectively clean the LED screen dust and other imprints.
Cleaning and maintenance is divided into three steps: The first step: vacuuming. First remove and remove the dirt and dust from the display mask surface. The second step: wet wash. Be careful not to spray the lotion directly on the screen. Instead, spray a small amount of cleaning solution on the cleaning cloth and gently wipe it in the same direction. It is also possible to scrub the lamp mask with a soft brush on the vacuum cleaner to clean the dirt. The third step: drying. Use a vacuum cleaner to dry the water marks left after the wet wash to ensure that the display mask is clean and dust-free.
