Why is my business sign not lighting up?
The most common cause is a failed power supply, followed by burned-out LED modules, a tripped breaker, a bad timer or photocell, or water getting into the sign. If only part of the sign is dark, it's usually one power supply or one section of LEDs. If the whole sign is dark, check the breaker and timer first.
How much does it cost to repair a business sign?
Most business sign repairs cost a few hundred dollars. Typical ranges are $150 to $300 for a service call and $200 to $500 to replace a power supply.
| Repair | Typical cost |
|---|---|
| Service call and diagnosis | $150 to $300 |
| Lift or bucket truck (if needed) | $100 to $300 extra |
| Power supply replacement | $200 to $500 |
| LED modules for one channel letter | $150 to $400 per letter |
| New LEDs for a whole storefront sign | $800 to $2,500 |
| Rebuilding a damaged channel letter | $300 to $900 per letter |
Typical industry ranges; your price depends on the sign, its height and what the technician finds.
Should I repair or replace my sign?
Repair it if the cabinet or letters are in good shape and the problem is lighting. Replace it if the structure is rusted or cracked, the faces are badly faded, or repairs keep adding up. LED signs commonly start losing brightness or power supplies around years 5 to 8, so a sign past that age with several failures may be worth replacing.
Can an old neon or fluorescent sign be converted to LED?
Yes. Most neon and fluorescent signs can be retrofitted with LEDs inside the existing cabinet or letters. An LED retrofit usually costs less than a new sign, uses less electricity and lasts longer. Ask for a quote on both a retrofit and a replacement so you can compare.
What should I check before calling for a sign repair?
Check the circuit breaker, the sign's on/off switch and the timer or photocell setting first. If those are fine, take a photo of the sign at night showing which parts are dark, and send it with your address when you request service. That helps the technician bring the right parts.
