The maintenance in front of the outdoor LED screen cabinet mainly includes the following aspects to ensure the normal operation of the LED screen and prolong its service life:
Cleaning and maintenance
1. Clean inside the box: For displays with low protection levels, especially outdoor screens, dust in the air enters the equipment through the ventilation holes, which will cause wear and tear or even damage to fans and other equipment. Therefore, it is necessary to regularly clean the dust inside the display to ensure that the inside of the device is clean.
2. Clean screen surface: After long-term use, dust and impurities will accumulate on the surface of the LED display, which will affect the display effect. When cleaning, choose a reliable cleaning kit that includes electrolyte, high-purity distilled water and antistatic fluid, which can effectively remove dust and stains from the screen. At the same time, avoid spraying water directly on the screen, but spray a small amount of cleaning liquid on the cleaning cloth first, and then gently wipe it in the same direction. Also unplug the main power cord to prevent electric shock before cleaning, and finally use a vacuum cleaner to blot up water droplets and water marks.
Fastening work
Since the outdoor LED display screen is a high-power-consuming equipment, in the process of multiple start-stop and operation, the terminal of the power supply part may be loose, the contact is not firm or the connection is virtually connected due to thermal expansion and contraction.
Therefore, it is important to regularly check the tightness of the connectors in the equipment and to ensure that the tightness is consistent by adjusting the fasteners with even and appropriate force.
Visual inspection
Make visual or measured observations on the appearance of outdoor LED display equipment, including checking whether there are damage cracks on the outer surface of the equipment, whether the angle is tilted, whether the communication and distribution cables are normal, and whether the fastener screws are loose and corroded.
For equipment with a high level of protection, it is also necessary to regularly check the integrity of its seals and the surface paint and rust of the steel structure of the outdoor screen.
Lightning protection
Regularly inspect the lightning rod and grounding line to ensure the effectiveness of the lightning protection facilities. Lightning protection facilities should be tested after lightning strikes, and if they fail, they must be replaced in time.
Heat dissipation and temperature control
Outdoor LED display is used for a long time in a high temperature environment, which is easy to cause excessive screen heating and damage to electronic components. Therefore, the environment in which the outdoor LED screen is installed should be well ventilated as much as possible to avoid direct sunlight and high temperatures.
At the same time, outdoor LED screens should also be installed with heat dissipation devices, such as fans or heat pipes, to enhance the heat dissipation effect and ensure the normal operation of the screen.
Regular software updates and corrections
When the outdoor LED display runs for about 5,000 to 10,000 hours, there may be problems such as display uniformity differences, inconsistent color and brightness attenuation, etc. At this point, you should consider making point-by-point corrections to improve the display.
Adequate preparations need to be made before calibration, including cleaning the LED display to remove dust and stains, replacing defective modules to ensure the display is working properly, and upgrading the receiving card to support calibration.
Through the above maintenance measures, the stable operation of the outdoor LED screen cabinet can be ensured, its service life can be prolonged, and a good display effect can be maintained.
