Posted in:

If your LED sign has stopped working, don’t worry—it’s often a simple fix! One of the most common culprits is the power cord or power supply.

An Easy Step-By-Step LED Sign Troubleshooting Guide

Step 1: Check the Power Supply

Your LED sign’s power supply is the device that plugs into the wall and provides the correct voltage to power your sign. If your sign isn’t working, this should be the first thing you troubleshoot.

1) Check to see if the power supply is securely inserted into the input port.

2) Verify the power supply is fully plugged into a properly rated wall outlet.

3) Toggle the on/off switch once steps 1 and 2 have been completed. Switches can wear out over time.

Step 2: Replace the Power Supply if Needed

If the sign still doesn’t turn on after checking the connections and outlet, the power cord or power supply is likely the issue. The good news? It’s a simple and inexpensive fix.

Steps to Replace Your LED Sign Power Supply

  • Check your warranty status. If you are in the 1 year warranty period, contact [email protected] for a replacement power supply.
  • If you are outside your warranty period, Look for a compatible replacement online. You’ll need to match the voltage and amperage listed on your old power supply (e.g., 110V, 2A, 60Hz).
