Read through the article to get an insight into the common problems that might happen to a LED wall and the solution.


Common Problems That Might Happen to a LED Wall


Due to the wearing and accidents, LED walls are usually prone to various issues and complications. Below are the common LED wall issues:


Problems with the LED module


The LED module may have various issues, including no displays due to loose power plugs, non-functional flat cables, or input signal cable breakdown. Furthermore, you realize that non-displaying module parts like lines and rows are missing. Besides not displaying on the single LED module and missing rows and lines, we've got other LED module problems. These issues include:


Static screen having single pixel missing, twinkling, or appearing dark.

You can use the X1 resistance technique to check the functionality of your multimeter. It allows you to check the beadwork functioning.


No display on various modules.

The problem results from improper signal cable connections. You can diagnose the problem by not realizing displays on the modules.


Color missing on the LED module.

It occurs due to a poor signal cable connection or a malfunctioning display module.


Color inconsistency on one row of the display module.

The problem results from the failure of the appliances or driver IC's pins to function properly.


Problems with the LED cabinet


When having the LED wall or screen, it has various LED cabinet issues. For instance, you may realize no display on your single cabinet, resulting from a power supply breakdown or a non-functional receiving card. Your LED cabinet may experience problems due to the following:


  • ● Break down of power supply to the different system units
  • ● Faulty receiving card. You can diagnose the issue with no display or visuals on the cabinet. The receiver should have the green indicator twinkling and the red indicator maintaining the lighting when functioning properly.
  • ● Poor signal cable connections


Problems with LED display


Your screen or wall may have various LED display complications resulting from various factors. Below are the common LED display problems:


No displaying on the whole LED display

The problem may result from insufficient AC power input, signal breakdown, or internet cable. Furthermore, controlling system breakdown, poor DVI cable connections, and signal cable can also result in the problem.


Garbled display on the LED screen

Poor connection between the sending and receiving cards is the main issue causing the problem. Besides the card issues, poor internet cable connection and improper studio settings can also cause the garbled display.


Overlapped or disordered displaying on the LED displaying

The overlapping display is a common problem that may result from poor signal and display connections or DVI connection issues. Furthermore, a faulty LED sending card and LED studio setting can also cause disordered displays on display.


Shaking or winkling displayed on the whole LED display

Experts reveal that your LED wall or screen may be having a winkling or shaking display if the ground wires break off or the cards are functioning abnormally. Furthermore, the signal, DVI, and internet cable issues can cause the problem.


Lack of or inconsistent displaying on some parts or the entire LED display

It's a common problem due to the non-functional sending and receiving of the card. Improper LED display systems can also cause inconsistent displays.


The other problems with LED display problems include the following:


  • ● Fuzzy pictures or low LED display screen brightness
  • ● LED display having garbled displaying for a few seconds after powering the screen
  • ● Each displaying unit shows the same content


Problems with the LED control system


Regardless of the appliance's quality or maintenance, your LED may experience various control unit problems. These problems may result from poor graphic processing unit settings, poor power supply, or the internet cable. Experts advise that you diagnose to understand the source of your issue.


How to Fix these Problems?


The first step in how to fix led wall if it is broken is to understand the sources of the issues before starting the fixing problem. Let's look at how you can fix the different LED wall problems:


Fixing problems with LED module


LED module problems result from various issues or sources, which require different procedures to fix the problems. Nevertheless, below are the possible ways you can use most LED module issues:


  • ● Ensure you connect the power supply contact or plug normally. Repair or repair the power supply plug if it's loose.
  • ● Reconnect the flat or input signal cable to ensure that it connects properly with the power line
  • ● Repair or change faulty power pins on the appliance to correct the lack of display on certain module parts. Repairing these pins will help to control or prevent short circuits.
  • ● Ensure the signal input is functioning normally. Before replacing the flat cable, you can try plugging the signal input in and out several times.
  • ● Consider connecting the LED wall's negative electrode to the red probe and the positive electrode to the black probe. However, starting the connections will be vital after understanding whether the LED lamp is functioning normally.
  • ● You can change the module for color missing to check if the problem persists.
  • ● Repair the driver IC by testing, removing the defect, and reducing the excessive solder.
  • ● You can also drive and replace a faulty circuit diagram on the LED wall.


Fixing issues with LED cabinets


Like LED displays, the cabinet usually has various issues from various sources. Below are appropriate tips on how to fix LED screen cabinets:


  • ● Check and connect the power supply properly. Ensure all the system and program's power supply function properly.
  • ● You can change the receiving card if there is no display on the cabinet. It'll be necessary if the card is functioning abnormally. You'll realize the abnormality in sending the signal if the green card switches off or keeps on lighting continuously.
  • ● Ensure there is a proper signal cable connection in the cabinets


Fixing LED display problems


Due to the different problems, including garbled display, and no displaying on the whole LED screen, we've got various solutions to LED display problems. The solutions include:


  • ● Turn on the power distributor swift if the screen doesn't have an AC power input. Turning on this power distributor will help solve the lack of AC power input issue.
  • ● Reconnect the signal cable if it breaks down. Experts advise reconnecting it until the card's green indicator starts twinkling normally.
  • ● Correct and ensure a normal LED receiving and sending card connection to deal with the controlling system breakdown.
  • ● Power off your screen, reconnect the DVI cable and reinforce the problem.
  • ● Correct any ground wire breaks off to solve complications between the LED screen display and the ground wire.
  • ● Ensure that you connect the internet cable appropriately to avoid influencing the displaying performance and resulting in inappropriate parameters.
  • ● Replug or replace the signal cable to enhance the connection to the cabinets
  • ● Set up proper LED studio software or tools and reconnect the signal cable to diagnose any mistakes in the DVI card setting and get appropriate options to solve them.
  • ● Resend the cascading file and plug the computer's internet cable on the output port adjacent to the LED sending card's indicator lamp.


Fixing problems with the LED control system


After diagnosis and establishing the source of the problems, below are the appropriate tips for fixing these issues:


  • ● Diagnose and install the graphic processing unit appropriately. Remember to follow all the guidelines and requirements to prevent the problem from recurring or creating more complications.
  • ● Ensure you achieve proper cable connections, including the PCI port, host control card, internet cable, or DVI cable.
  • ● Choose the right power supply for the LED display and computer's control system based on the requirements.
  • ● Restart the control system to check if the green indicator keeps on flashing
  • ● Reset or uninstall the software instruments to ensure the proper functioning of the LED control unit or system.
  • ● Confirm if the internet cable is functioning appropriately. The cable must be approximately 100 meters within to enhance proper functionality.
  • ● Ensure the appliance's power lamp is compatible with the system unit board
  • ● Ensure that you turn on the power lamp. You can check if the defined line port is compatible with the system unit board.
