How to maintain the LED display screen?
Do you know how to maintain the LED display? Do you want to know the authoritative opinions on the daily use and maintenance of LED displays? Galaxyav is a factory with more than 20 years of LED display manufacturing history, we have rich experience in LED design, production and problem solving. This article will tell you the correct LED display maintenance and maintenance methods.
Like other electronic equipment, the LED display screen can be properly maintained and maintained to prolong the service life of the display screen. At present, the problem of LED display failures is mainly caused by two aspects. On the one hand, in order to obtain more market share at low-end prices, LED display manufacturers use lower-quality raw materials when producing LED displays. , resulting in premature aging of this part of the electronic components can not work properly. On the other hand, the failure of the LED display caused by the user’s incorrect operation or some unexpected situations during use.
Maintenance work of LED display
The maintenance work of LED display is mainly divided into 4 aspects, namely regular security inspection of LED display, regular cleaning of LEX display, tightening inspection of display connector and regular surface cleaning of display.
A. Regular security inspection of LED display
The “monthly inspection system” can be adopted for the security inspection of ordinary LED display screens, while the “weekly inspection system” is adopted for large-scale LED electronic screens.
1. Regular on-site inspection by technicians once a month to inspect and maintain the system.
2. For outdoor display screens, due to the possibility of damage caused by natural factors such as wind, rain, thunder, electricity, etc., the frequency of security inspections should be increased.
3. During the maintenance service period, the maintenance problem will be solved within 8 hours for general failure, and the major accident should not exceed 24 hours. If the maintenance needs to replace the module and other accessories, it should not exceed 24 hours. After the maintenance is completed, use the service to ensure that the large screen does not have faults above the module level (such as module color cast, module black, one column not bright, etc.).
4. The security inspection of LED display screens for major events requires specific LED display screen technicians to manage and control them in real time on site.
B. Cleaning up the display
For LED displays with harsh environments, especially outdoor LED displays, dust in the air can easily enter the device through the ventilation holes, which will accelerate the wear and even damage of fans and other devices. Dust may also fall on the surface of the internal control devices of the display screen, reducing the thermal conductivity and insulation performance. In wet weather, the dust absorbs moisture in the air and will cause a short circuit; it will also cause mildew on the PCB board and electronic components for a long time, resulting in equipment damage. The technical performance is degraded and malfunctions occur. Therefore, the cleaning of the display screen may seem simple, but it is actually a very important step in the maintenance work.
C. Regularly carry out the tightening work of the display connector
LED electronic screen belongs to high power consumption equipment. After running for a period of time, due to repeated start and stop and operation, the connection terminals of the power supply part will be loose due to cold and heat, the contact is not firm, and a virtual connection is formed. In severe cases, it will heat up, even Ignite the plastic components next to it. The signal terminals will also loosen due to changes in ambient temperature and heat, and moisture erosion will lead to poor contact, which will lead to equipment failure. Therefore, the connectors of the LED electronic screen must be regularly tightened. When adjusting the fasteners, the force should be even and appropriate to ensure that the fasteners tightly connect the various electronic components.
D. Regularly clean the display surface
LED electronic screen cleaning is a high-altitude operation, and a professional cleaning team is required. The cleaning operation adopts the method of high-altitude sling or hanging rail, and is equipped with professional cleaning equipment. The cleaning staff selects different cleaning agents according to the different dirt on the screen for targeted cleaning, so as to ensure that the LED lamp and the mask are not damaged. Complete the cleaning of the display. There are two points to pay attention to when preparing for cleaning: 1. Before cleaning, you need to unplug the power cord. Second, the choice of cleaning solution, the cleaning solution generally includes electrolyte, high-purity distilled water, anti-static solution, etc., the pH should be neutral detergent, so as to effectively clean the dust and other stains on the screen.
The specific cleaning and maintenance is divided into three steps:
Step 1: Vacuuming. Suction and sweep the dirt and dust on the surface of the display mask first.
Step 2: Wet cleaning. Be careful not to spray the lotion directly on the screen, but to spray a little cleaning liquid on the cleaning cloth, and then gently wipe in the same direction. You can also use the soft brush on the vacuum cleaner to brush the lamp mask to remove the dirt.
Step 3: Drying. Use a vacuum cleaner to absorb the water marks left after wet cleaning to ensure that the display mask is clean and dust-free
Maintenance of LED display
When the LED display is used indoors, it is necessary to control the indoor temperature and humidity. In countries or regions with humid environments, it is best to install dehumidification equipment indoors when using LED displays, otherwise, moisture will corrode related electronic components after entering the LED display, causing permanent damage. This permanent corrosive damage can only be replaced by the corresponding LED display module and cannot be repaired, which will bring great economic losses to users.
A stable power supply is a key factor for the normal use of the LED display. Unstable voltage can easily cause the LED display to malfunction, and in severe cases, it will also cause the display to short-circuit and burn. Therefore, when the LED display screen encounters a force majeure power failure during use, the power switch should be disconnected in time. Wait for the external environment to stabilize and then turn on the power switch again.
When using the LED display to play the screen content, it is recommended not to keep the screen content in all white, all red, and all green lights for a long time. Because these full-bright images require large current support, long-term use may cause the power cord to overheat and damage the LED lamp beads
If the LED display has not been used for a long time, it is recommended to arrange for someone to turn on the LED display regularly. In the wet and rainy season, it is generally recommended to open it once a week, and under normal circumstances, it can be opened once a month. After the LED display is turned on, the temperature generated by its normal operation can evaporate part of the environment and the humid gas inside the device, thereby prolonging the service life of the LED display.
The maintenance of the LED display screen should be carried out by professional technicians, and the manufacturer’s maintenance manual should be followed during the use and maintenance process, and unauthorized operations are not allowed. If you have lost the operation manual of the LED display screen or do not have professional technicians, you can fill in the relevant information in the form below if you want to carry out professional maintenance and maintenance of the LED display screen.
