If it fails: the first hour
What the site contact should do before the technician arrives.
- Restrict access to the area below or near the sign
- Photograph the damage and the surrounding area
- Call for emergency temporary securing if the sign poses a falling risk
- Note whether the sign is still receiving power for the technician
What fails
What a service call includes
- Troubleshoot electrical circuits before assuming a lighting failure is cosmetic
- Replace individual LED modules or full lighting sets to match existing color and brightness
- Repair or replace transformers, drivers, and power supplies
- Replace cracked or faded sign faces and reapply vinyl graphics
- Reseal wiring connections against moisture intrusion
- Assess and repair structural leaning at the pole or foundation
- Diagnose and repair digital message center module or control faults
- Perform temporary securing of storm-damaged signage before permanent repair
Preventive checklist
The items a maintenance program should carry for this system. Build a combined checklist across systems with the checklist builder.
Quarterly
- Visual check for dark or flickering sections at night
- Inspect cabinet faces for cracking or fading
Annual
- Full electrical inspection of transformers and wiring
- Structural check of pole and monument sign mounting
- Digital display module and weatherproofing inspection
What it costs
| item | typical range | what moves it |
|---|---|---|
| LED module replacement (per letter or section) | $75 to $250 | Cost depends on letter size and whether color matching is needed. |
| Transformer or power supply replacement | $200 to $600 | Higher for larger signs requiring multiple transformers. |
| Cabinet face replacement | $500 to $2,000 | Price depends on face size and whether custom graphics need to be reprinted. |
| Vinyl graphic reapplication | $200 to $700 | Varies with size and complexity of the design being replaced. |
| Structural leaning repair (pole or monument base) | $800 to $3,000 | Depends on whether the foundation needs partial rebuild or just re-anchoring. |
National ranges. Local labor, access, after-hours timing and materials move them. Multi-site programs usually price below one-off calls.
When this is an emergency
A sign that has come loose from its mount or a leaning pole sign near a walkway or drive lane counts as an emergency due to the risk of it falling.
How to choose a provider
- Ask whether the provider stocks common LED modules and transformers for one-visit repairs
- Confirm they troubleshoot electrical issues rather than only replacing visible components
- Ask about color and brightness matching when replacing partial LED sections
- Get a quote that separates electrical, structural, and cosmetic repair costs
- Ask about response time for a sign that is dark or leaning
Questions
Why are only some letters lit on the sign?
This usually means individual LED modules have failed while the rest of the circuit is intact, which is repairable without replacing the whole sign.
Why does the sign flicker at night?
Flickering often points to a failing transformer or a loose wiring connection rather than the LEDs themselves, and it tends to get worse until repaired.
Can a leaning pole sign be straightened?
Sometimes, if the foundation is sound and just needs re-anchoring, but a foundation that has cracked or shifted significantly may need partial rebuilding first.
How urgent is a dark sign at night?
It is not a safety emergency in most cases, but it does affect visibility to customers, so many providers treat it as a priority repair rather than a true emergency dispatch.
