LED Advertising Screen Operation Procedures and Common Problems
As a dazzling jewel in the city night sky, LED advertising screens, with their high brightness, vibrant colors, and dynamic visual effects, have become an indispensable medium for modern commercial communication. For users new to or already using this equipment, understanding the standard operating procedures and mastering troubleshooting methods for common faults is crucial to ensuring smooth advertising and extending the equipment's lifespan.
First, the standard operating procedure typically consists of the following core steps:
1. Power Distribution and Power-On/Off Management: LED screens must adhere to a strict power-on/off sequence. When powering on, first turn on the signal source (such as the playback controller), and after it has started up, turn on the main power supply for the display screen, and finally turn on the power supplies for each unit cabinet in sequence. The power-off sequence is the reverse: first turn off the display screen power supply, then turn off the signal source and computer. This effectively prevents the surge current at power-on from impacting the screen and avoiding "bright spots" or "burn-out" phenomena.
2. Sending Card and Receiving Card Settings: Open the LED display screen control software (such as Nova, Lingxingyu, or other mainstream systems) on the control computer. First, load the sending card parameters and set the correct resolution and refresh rate.
Then, the identification is performed automatically or manually using software.
