Tips to Keep Your LED Screen Healthy

November 28, 2023

by Editorial Team

LED screens have become ubiquitous in today’s digital landscape, serving as the primary display technology in various applications, from large outdoor billboards to personal devices. To ensure these screens continue to deliver high-quality visuals and longevity, proper maintenance is essential.

With our extensive experience in deploying digital signage in outdoor environments, we excel at delivering outstanding results, even in challenging circumstances.

Electronics do not last forever and require a proactive maintenance team. Maintenance service ensures optimal performance of your screens through regular inspections, cleaning, and repairs.

How to Maintain Your LED Display

Proper maintenance is important for LED displays to ensure longevity and optimal performance. This section outlines essential tips, such as regular cleaning to prevent dust buildup, investing in professional repair services, and adhering to temperature and humidity guidelines.

Keep It Clean

Avoid scratching the screen or damaging the delicate LED pixels by using the right materials for cleaning.

Repair and Service

Certified technicians at OneStop Signage can repair or replace damaged diodes, modules, shaders, receiving cards, hub boards, power supplies, and other components.

Regular Maintenance

Make sure that the vendor you engage for regular maintenance service provides a detailed report after each check and is also responsive in the event of urgent repairs.

Other General Tips for LED Maintenance

  • Temperature: LED screens perform best at 30°C.
  • Humidity: At 60% humidity, LED screens perform optimally. Higher humidity increases the likelihood of component corrosion, which increases the likelihood of short circuits.
  • Rodents can damage connection wires.
  • Power Source: Ensure that the power source is properly grounded and protected from electrical surges regularly.
  • Powering On and Off: LED screens have a certain sequence of operation that ensures a longer lifetime. When you are either turning the screen on or off, the control computer should go first, and then the screen itself.

How to Maintain Outdoor LED Screens in Bad Weather

Outdoor LED screens face unique challenges in inclement weather. Heat dissipation and lightning protection measures are essential to prevent circuit shorts and other weather-related issues.

  • Equip Heat Dissipation Equipment

If the LED screen’s heat dissipation problem is not resolved quickly, a circuit short will most likely occur, especially when temperatures rise. 

To aid in heat dissipation, LED screen manufacturers should strive to develop hollow shells and include an air conditioner or fan in their LED displays. As a business owner, you should insist on having the LED display screens installed in a well-ventilated area. Heat-dissipation equipment can be installed on the exterior if necessary.

  • Include lightning rods and lightning protectors.

Lightning protection, such as installing lightning rods and grounding wires on the support structure of outdoor LED display screens, is very important. A single-phase or three-phase power lightning protector can effectively stop the lightning current on the power line.

Common Faults and Solutions

Understanding common LED screen faults, such as “dead lights” and “caterpillars,” allows for quick identification and resolution. Our certified technicians are equipped to handle these issues, ensuring your LED screen’s continuous functionality.


“Deadlight” refers to one or more lights on the light surface of the LED display screen that are not turned on. This is classified as either full-time or partial-color nonlit. Generally, this may be due to a faulty light, dampness, or a damaged RGB chip.


The term “caterpillar” refers to a long, bright red strip that appears when the LED display screen is turned on but no input source is present. This problem is caused by an internal lamp chip leak or a short circuit in the IC line behind it. This issue is usually resolved by blowing hot air with a hot-air gun along the discolored “Caterpillar” with electric leakage. 

Missing Color Block

If you see a spot with different color blocks appearing when the LED display screen plays normally, it could probably mean that the color IC was burned. The solution will be to replace a new IC.

Partial or Large Black Screen 

When the LED screen is not displaying content (i.e., a black screen), it could be an issue with the power supply, power cord, or simply a connectivity issue. In many cases, reconnecting the power cord solves this issue. If that does not work, you will need to check the status of your power supply and power cord.

LED screens have revolutionized information and entertainment consumption. By following proper maintenance tips and being aware of common faults, you can enjoy vibrant visuals for years.
