Maintenance
1. Before the maintenance of LED display, the power supply of the display must be cut off the power of the screen
body during installation and maintenance to prevent electric shock and injury, and avoid short circuit of the live
parts of the PCB board against the metal frame;
2. Please pay attention to protect the module surface when using the front maintenance tools, and do not damage
the module surface;
3. Please pay attention to anti-static measures when using the front maintenance tools, and wear anti-static
gloves to prevent static damage to LED;
4. Please pay attention to the battery power before using the front maintenance tools;
5. Pay attention to take out the module vertically to avoid damage and falling of LED lamp due to collision with edge
of adjacent module.
6. Vacuum front maintenance tools cannot work continuously for a long time. After taking out the module, please
turn off the power supply of vacuum front maintenance tools in time to avoid burning out the motor.
The main process of front display maintenance is as follows:
Step 1: Turn off the power of the display;
Step 2: Place the tool on the surface of the module after connected it to the AC power cord , press the switch and
the mark "I" is facing downwards , then the tool starts to pump air
；
Step 4: Move the LED panel to the safety plane, press the switch key, and the switch mark "O" is facing downwards,
remove the tool after adsorption force is released. At this time, the LED panel, HUB board and control card can be
maintained.
Step 3: After about 3-5 seconds of air extraction, the vacuum sucker and the LED panel are tightly attached; Pull out
the LED panel vertically by force. Hold the LED panel with one hand to prevent it from falling. Hold the vacuum sucker
handle with the other hand. Make sure not to touch the adjacent LED panel when pulling out the LED panel, so as to
avoid collision and damage to the LED;
