LED light pole screens are essential to smart city infrastructure. They share real-time information, support public safety, and operate with energy efficiency. But when the built-in power supply fails, the screen can stop working or even become dangerous. Here’s a clear guide to dealing with a faulty power supply safely and effectively.
If the screen blacks out, flickers, or shows partial failure, disconnect the power right away. Locate the distribution box and follow proper shutdown steps. Never inspect or touch the unit while powered—it can cause serious hazards. If unsure, seek help from local management or utility staff.
Once power is off, carefully assess the condition:
Wiring – Replace cracked, burnt, or loose wires with ones of the same specification.
Module appearance – Look for bulging, burnt marks, or deformation.
Voltage check – Use a multimeter to confirm whether the output matches standard values.
Keep records of issues and test results. These notes will be useful if repairs require professional help.
Minor issues – Damaged wires or blown fuses can be replaced if you have the skills and follow safety rules.
Power module failure – Contact the manufacturer or certified technician. Internal circuits are complex and should not be handled without training.
Share your recorded findings so technicians can prepare parts in advance.
If replacement is necessary, always match the rated power, voltage, and current of the original supply. Only professionals should perform this task. The process includes:
Disassembly – Remove the faulty unit carefully.
Installation – Fit the new module securely, with all connections tightened.
Double-check – Inspect wiring and mounting before restoring power.
After installation, power on the screen:
Confirm normal startup with no flicker or distortion.
Verify voltage and current levels using proper equipment.
If problems remain, switch off and recheck components.
Dealing with a damaged LED light pole screen power supply demands caution and technical knowledge. Always put safety first, document your findings, and call professionals when needed. Proper handling not only restores functionality but also ensures the long-term reliability of LED systems in smart city environments.
