How to quickly identify and handle damaged LED display screens?

LED screen as a very wide range of uses now display, it is high-definition and exquisite picture quality and free and varied shape by the major industries, but LED screen as electronic equipment, will inevitably be used in the process of some adverse circumstances, resulting in damage, these damages may be caused by the environment, it may also be the use of the process because of some inappropriate maneuvers lead to.

Either way, we understand these common types of LED screen damage, can help us in the process of use, better to avoid the behavior that may lead to damage to the LED screen, and how to deal with the problem after the damage.

Recognize LED screen damage

When the LED screen is damaged there are usually some very obvious signs, the most intuitive judgment is that the image does not normally display several states.

Similar to the LED screen image lines, black dots, screen flicker, screen ghosting, etc., these are the most intuitive signs of screen damage, we can be based on these incorrect display to determine the cause of the damage, so as to solve and deal with the problem, and to avoid secondary damage.

LED screen damage types

At present, we will be common causes of damage to the LED display screen is categorized into four categories, to understand the causes of damage to these four types of damage can help us to repair the damaged screen as soon as possible, as well as how to usually correctly clean and protect our purchased LED screen, so that the screen has a longer service life.

Physical damage

Physical damage refers to the external collision or cuts and other physical factors lead to screen damage, in the daily handling of the LED screen or installation process, hard impact or extrusion may lead to the outside of the LED screen board LED beads broken or internal parts broken, and ultimately the LED beads can not be correctly lighted, can not complete the image.

Bad dots

There are two kinds of bad dots, one is a single pixel can not display the same color as the other pixels around, the LED beads are always black, this kind of we call “bad pixel”.

One is when a single pixel changes to a certain color during playback, and the subsequent colors do not follow the screen to change, but continue to show the same color, which we call “stuck”.

If it is a “stuck” pixel, it can be solved by refreshing the screen pixels with the application program, but if it is a “bad pixel”, it is necessary to replace the module.

Environmental damage

Environmental damage is a constant challenge for LED screens, usually caused by moisture, dust and sunlight. Although LED modules are available in outdoor series, prolonged exposure to moisture, dust, and sunlight can still reduce the life of an LED display to a certain extent.

Screen discoloration

When the LED screen is affected by the environment and the quality of the screen deteriorates, the colors of the LED display will be distorted, resulting in an extremely strange image being presented.

This can be caused by humid environments or prolonged exposure of the device to high temperatures that cause the quality of the LED display to deteriorate, but it is not completely damaged.
These damages are irreversible, so we need to pay attention to keep the LED screen from moisture and avoid dust as well as direct sunlight in our daily use.

Temperature damage

Excessive sudden changes in temperature may cause damage to the LED screen, whether it is a sudden change into too high a temperature or a sudden change into too low a temperature, will lead to various types of problems with the LED screen.

Melting and Deformation

When an LED screen is baptized by too high a temperature, there will be noticeable distortion on the screen as well as some areas of melting and delamination.
When LED screens are in extremely low temperatures, the systems of the LED screen can be damaged and not function properly.

Electrical damage

Electrical damage is also a common type of damage to LED screens and is usually caused by faulty circuits or damaged power supplies.

Flickering Screen

Whether the LED screen flickers rapidly or regularly, it is not suitable for the audience’s viewing experience, and it is easy for people to feel eye fatigue. The dimming of the LED screen is usually caused by electrical damage, which may be caused by unstable power supply, incompatible software, or malfunctioning circuits.

Pay attention to confirm the power supply before use, in addition to outdoor LED screen should pay attention to avoid lightning strikes.

Lines on the screen

When the circuit board inside the LED screen is damaged, there may be a lot of lines and stripes on top of the LED display, which can be multiple angles and multiple colors, resulting in the screen can not be viewed, and sometimes the graphics card malfunctions, which can also lead to such situations.

How to deal with LED screen damage

Step 1 – Determine the cause of screen failure

First of all, you need to turn off the power of the LED screen, and then check whether there is physical damage to the screen; check whether the temperature of the LED screen is normal, make sure that it is not a problem with the ambient temperature and the temperature of the screen; reopen the power supply to check whether there is a problem with the power cycle, and whether all kinds of interfaces are connected to the stability of the interface; and finally, you can try to update the software, and sometimes incompatible versions of the software can also lead to the failure of the display.

Step 2 – Contact a professional

When troubleshooting does not get the answer, do not easily try to fix it yourself, one reason is that it may pose a threat to their own safety, and the second is that it may cause more unnecessary damage to the LED screen, so it is still necessary to contact a professional to fix it is more secure.

Step 3 – Evaluate the need for repair or replacement

LED screen if the software is incompatible or unstable power supply, try to update the software or replace the LED display power supply; if the device itself is damaged, you need to replace the corresponding module of the LED screen, it is worth mentioning that, usually in the purchase of LED display, the manufacturer will give some free LED module, as a subsequent replacement of the spare module, so the replacement of the module basically do not have to buy a second time and incur costs.

Step 4 – Some good tips and experiences

Sometimes, the LED screen has a display failure, not necessarily the equipment is damaged, it may be some software problems, or power supply problems, we can try to troubleshoot by ourselves, to avoid unnecessary replacement resulting in a waste of resources.

Tips for Maintaining LED Screens

• -Installation should be done gently and without violence.
• –Clean the screen regularly
• -Ensure the power supply is stable
• Keep software up-to-date
• -Do not leave your LED screen in extreme ambient temperatures.

Conclusion

Paying attention to protecting the LED screen during transportation, installation, and use of the LED screen is the key to prolonging the service life of the LED screen; if you find that there are problems with the LED screen display, you can do a simple troubleshooting on your own first, and if you can’t solve it, you can look for an expert to deal with these problems.

LED screen has been famous for its long service life, unless the extreme circumstances lead to damage to the LED screen, the general LED screen can be stable for a long time.
