First: Inspect

General LED display inspection take the "monthly inspection system",

and large-scale LED display maintenance take the "weekly inspection system".

The specific maintenance are as follows:

1. LED display screen maintenance, including lamp, module, power cable,

signal cable, power supply, receiving card;

2. Maintenance of LED display control system, including controller, Video processor,

optical fiber conversion card, distributor, sending card;

3. Special playback operation software for LED display screen,

including maintenance and upgrade of the software;

4. Periodic (once a month) on-site inspection of technical personnel

to check and maintain the system;

5. Safeguarding major events: The company's technical staff guide to

ensure the smooth development of on-site activities.

6. For outdoor LED display, damage caused by natural factors

such as wind, rain, thunder, electricity, etc. is not covered by the warranty.

The owner needs to insure the insurance company, and the insurance company will pay for it.

7. During the maintenance service period, general failures shall be resolved

within 8 hours of repair problems, and major accidents shall not exceed 24 hours.

The replacement of modules and other accessories for maintenance shall not

exceed 24 hours. After the repair is completed, One Service ensures that the large screen

does not appear faults above the module level (such as module color cast, module black,

one column is not bright, etc.), normal playback.


Second: Clean up

For LED display screens with lower protection levels, especially outdoor screens,

dust enters the device through the ventilation holes, which will accelerate wear

and even damage to fans and other devices. Dust will also fall on the surface of

the control device inside the display, reducing thermal conductivity and insulation performance.

In wet weather, the dust absorbs moisture in the air and causes a short circuit; for a long time,

it can also cause mildew on the PCB board and electronic components,

resulting in a decline in the technical performance of the device. error occured.

Therefore, the cleaning of the LED display screen seems to be simple,

but it is actually a very important part of the maintenance work.


Third: Fastening

The LED display is a high power consumption device. After running for a certain period of time,

due to repeated start and stop and operation, the terminals of the power supply part will be loose

due to cold and heat, and the contact will not be firm, forming a virtual connection.

Ignite the plastic element next to it. The signal terminals will also loosen due to changes

in the ambient temperature, resulting in poor contact due to moisture erosion,

which will lead to equipment failure. Therefore, the connectors of the LED display

must be tightened regularly. When adjusting fasteners, the force should be even

and appropriate to ensure sturdiness and effectiveness.


Forth: The display surface clean

Visually inspect and inspect the LED display in two states: bright and black.

Including: whether the surface of the display screen is contaminated,

the purpose is to remove the influence of surface dirt on the luminous characteristics;

whether there are damage cracks on the surface of the display screen;

whether the communication distribution cable line is normal; for equipment with a high degree of protection,

although the high reliability is selected Components and connectors,

but their tightness has become a key factor, therefore, the integrity of the seal

should be checked regularly; for outdoor screen steel structure,

the surface paint and rust should be checked; for outdoor screen surface pollution is particularly serious,

but also Clean the display surface.

LED display screen cleaning is a high-altitude operation, and a professional cleaning team is required.

The cleaning operation adopts high-altitude sling method (commonly known as spider man) or sling blue,

and is equipped with professional cleaning equipment. The cleaning staff selects different cleaning agents

for specific cleaning according to the different dirt on the screen to ensure that the LEDs are not damaged

Complete the cleaning of the LED display under the premise of the mask.


There are two points to note when preparing for cleaning:

1. Before cleaning, you need to unplug the power cord.

Second, the choice of cleaning fluid, cleaning fluid generally includes electrolyte,

high-purity distilled water, antistatic fluid, etc., to choose good quality,

in order to effectively clean the dust and other stains on the LED screen.


Cleaning and maintenance are divided into three steps:

Step1 : vacuuming. Firstly remove and clean the dirt and dust on the surface of the display screen mask.

Step 2: Wet cleaning. Be careful not to spray the washing liquid directly on the screen,

but spray a little cleaning liquid on the cleaning cloth, and then wipe gently in the same direction.

You can also use a soft brush on the vacuum cleaner to scrub the lamp mask to clean the dirt.

Step 3: drying. Use a vacuum cleaner to absorb the water marks left after wet washing to ensure

that the display mask is clean and dust-free.
