Troubleshooting Tips
for Installation issues
Shadowing:
• Wire covering LED lens
• LEDs not Spaced Properly
• Product vs. Depth of the letter not correct
Sign or Row Does Not Light After Installation:
• Check Connection from Power Supply
• Check Power Supply Leads and Jumper Wire Connections
• Check to be sure output wires are connected with proper
polarity
Sign Does Not Light:
• Check Output Voltage of Power Supply with a Voltmeter
• Check Input Voltage going into the power supply with a volt
meter
• Check all Connections and Seal/Cap all Loose/Exposed Wires
Troubleshooting Tips
for Installation issues (cont’d)
Modules Are Dim:
• Check to be sure the Power Supply are not overloaded by
running more LED’s then recommended
One Module does not light but the others do:
• The system is designed so if one module doesn’t light, it will not
cause the entire row of LEDs to go out.
Flashing and Flickering:
• Overloaded power supply (too many feet/modules on a power
supply)
• Possible wire shorting out
LEDs do not light but a meter reading at the end of the string reads the
proper low voltage
• LEDs possibly hooked up to high voltage, LEDs have been
destroyed, however there is still continuity in the line.
