If the outdoor LED display is broken or damaged, it should be replaced in time, especially the screws, pins, load-bearing beams, etc.

Outdoor LED display screens regularly inspect the screen body and the surface of the solder joints of the steel structure to see if there is any peeling off. If there is any peeling or rust problem, it should be coated with anti-rust paint or anti-rust paste in time.

The power supply of the LED display should be stable and the grounding protection should be good. It cannot be used in harsh natural environments, especially under severe thunderstorms. The reliability of lightning rods and grounding systems should be checked regularly.
