With the rapid development of LED technology, large pitch outdoor products have gradually become indoor close range visible LED small pitch display screens, increasingly replacing DLP, LCD splicing, and projection products. Especially with the rapid development of smart cities and security industries, as well as the backdrop of digital enterprises and the digital age, the demand for indoor display hardware is increasing.

In the field of LED small pitch display screens, we provide narrow pitch product designs with different solutions. During this process, many customers have inquired about the daily maintenance and upkeep of LED small pitch display screens. Let's take a look below.

1、 Common knowledge of opening/closing LED small pitch display screen maintenance

Steps for opening/closing the screen

2、 Daily routine maintenance of LED small pitch display screen

1. It is recommended to check the ambient temperature and humidity of the monitor every day to ensure they meet the working conditions.

2. If the monitor and auxiliary equipment are used at least twice a week, and the monitor is not used for 2 hours or 14 days each time, perform a warm-up operation before reusing it.

3. In order to achieve display effect, it is recommended to use an anti-static soft brush to clean the dust on the surface of the monitor every month.

4. Check the components of the distribution board every quarter, inspect the contact firmness and safety of the power signal line of the monitor, and check whether the grounding of the monitor is good.

5. Check the firmness of the steel structure annually.

3、 Common faults and solutions of LED small pitch display screens

1. Module dead zone light or backlight light

Reason:

Dead lights below 50ppm are a normal phenomenon.

The light during installation and suddenly dropped during use.

2. Module color bar

Phenomenon:

The module has vertical bar color abnormalities: high brightness, dark brightness, constant brightness, red green blue color abnormalities.

Reason: Abnormal module chip, internal short circuit of a certain column of light beads, short circuit of PCB board circuit, and compression between modules.

3. Color code/color code appearing on the module

Phenomenon: The module exhibits abnormal rectangular/elongated color areas.

Reason: One of the module integrated circuits is abnormal.

4. There is no calibration data in the module

Phenomenon: The phenomenon of flower screen/mosaic or long white hair appearing on a module by module basis.

Reason: The module did not upload calibration data or calibration data is missing. Maintenance method:

5. Abnormal unit signal/power connection

Symptom: A single module has no black display or incomplete display.

Reason: The 5V power and signal lines of this module are connected abnormally.
