The LED module is used in many industries, we can be found in schools, conference rooms, hospitals, banks, etc.
Routinely maintenance is obviously very important for LED module, not only can extend the service life of LED display module, but also can reduce its failure rate.
So, how to carry out the Routinely maintenance?
This article introduces you the correct way to use LED display module, and how to carry out routinely maintenance, and the way to deal with little failures.
Let’s get started!
Part One Notes for using the LED module
1. LED module on/off screen operation
The LED display module has a strict order of operation when it is used.
Please keep in mind the following tips for operation.
(1)Turn on the screen
→Step 1 Launch the display power distribution box
→step 2 Activate the control computer
→step 3 start the transmitter box
→step 4 Turn on the video processor
(2)Turn off the screen
→Step 1 Turn off the video processor
→Step 2 Switch off the transmitter box
→Step 3 Shut down the control computer
→Step 4 Close the display power distribution box
If you turn off the computer and LED display first, it will cause the burn of LED beads.
In addition,the interval time should be more than 2 minutes when switching on and off the screen.
2. The use time of the LED module
The LED display rest time is recommended to be greater than 2 hours per day.
In the rainy season, the LED screen is used at least once a week or more.
This is to avoid LED display if not used for a long time, the internal components of moisture, the next time you turn on the words will cause a short circuit.
If the screen is not used for 14 days, please preheat it before using it again.
(2) How to preheat the LED display?
At 30%-50% brightness west, let the LED display preheat for 4-8 hours, then adjust to normal brightness (80%-100%) to light up the screen body.
If the screen body is not used for more than 7 days, it should be preheated for more than 12 hours at 30%-50% brightness, and then adjusted to normal brightness (80%-100%) to have no abnormalities when used.
3. Other notes
(1)Not display single Color for a long time
LED screens should not play a single color over 30 mins, such as all white, all red, all green, etc.
Otherwise, it is easily lead to the overheating damage to the LED module’s beads.
(2) Safe power supply
In harsh natural conditions, such as strong lightning weather do not use the LED display.
LED module is prohibited to use AC power supply, the positive and negative poles of the power supply must not be connected to each opposite.
Ground wires and neutral wires must be installed in place to avoid serious circuit accidents.
(3) Away from sharp objects
The surface of the LED module is fragile and needs to avoid scratching.
Therefore, when using the LED display, we should keep all sharp objects away.
Part Two 3 points for maintaining the LED module
It is necessary to prevent insect bites, and not to let the insects cause damage to the wiring of the LED module.
So the insecticide can be placed when necessary.
Storage also has requirements for temperature.
After the unpackaging of the LED module, the LED products shall be stored in an environment with temperature <30℃ and humidity <60%.
2. How to clean the LED module?
In long-term use, LED modules can accumulate more dust or other unclean things on the screen.
This requires regular and timely cleaning to prevent bad effects on viewing!
So, how do you clean the LED module?
It is recommended that you use a soft bristle brush to gently clean the dust from the surface of the LED screen.
If there are stubborn stains, do not use water or too much alcohol (including other cleaning products) directly to clean the LED display module, which may cause great damage to the LED beads or internal wires.
Our suggestion is that you can use cleaning products specifically for cleaning LED displays to help you remove stubborn stains and prevent LED modules from being damaged.
3. Routine maintenance
Daily maintenance is very necessary, the following will introduce you in detail to the common troubleshooting of LED modules.
If you do not know much about the wiring, we recommend that you do not repair modules by yourself.
As soon as possible to seek the help of professionals is a better choice.

Part Three Troubleshooting of the LED module
1. Dead beads in the LED module
Below 50ppm of dead lights, is a normal phenomenon.
In the LED module installation, there is also the possibility of dead lights due to accidental scuffing.
(2) Maintenance method
2. LED module display abnormalities
The module has a vertical bar shape color abnormality.
Including high brightness, dark brightness, constant brightness, and red, green and blue color abnormalities.
Module chip abnormal, the column of a certain lamp bead internal short circuit, PCB board line short circuit, extrusion between modules.
A rectangle/long strip of color abnormal area appears on the module.
One of the ICs on the module is abnormal.
(2) Maintenance method
Replace the problem module with a spare module, and upload the new calibration data.
Mark the reason for the repair on the replaced module and mark the exact coordinates of the module on the screen.
3. Module without calibration data
In the module as a unit, there is a mosaic or white and gray spot.
The module has not uploaded calibration data or the calibration data is lost.
(3) Maintenance method
Re-upload the calibration data of the module or re-upload the calibration data of the whole screen.
4. The brightness of the whole screen is inconsistent
The brightness of the whole screen is inconsistent.
The configuration file is not completely consistent.
(3) Maintenance method
Send the correct configuration file to the whole screen, or reset the brightness setting of the whole screen.
