Professional LED & Lighted
Sign Repair in NYC & NJ
LED and lighted signs are the backbone of modern commercial signage — energy-efficient, bright, and long-lasting. But they are not immune to failure. Dead modules, failing drivers, water ingress, color inconsistency, and power supply problems can turn your bright storefront into a dim, patchy embarrassment that drives customers away.
Metro Sign Services specializes in diagnosing and repairing all types of LED and illuminated signage. Our technicians carry the most common LED modules, drivers, and power supplies on their trucks, so most repairs are completed during the first visit. We work on every brand and configuration — from simple LED open signs to complex multi-zone illuminated displays.

What Makes LED & Lighted Signs Fail
Lighted signs span multiple configurations — LED module grids, cabinet light boxes, RGB programmable displays, fluorescent-illuminated cabinets, and backlit channel letters — each with its own components and failure points.
In NYC and NJ, freeze-thaw cycles crack seals, coastal humidity corrodes PCB traces, subway vibration loosens wiring terminals, and voltage spikes from aging infrastructure burn out drivers prematurely. Knowing exactly what type of sign you have and what the local conditions do to it is what determines whether a repair holds — or fails again in six months.
Why Choose Us for LED & Lighted Sign Repair
Our service vehicles carry the most common LED modules, drivers, and power supplies. This means most LED sign repairs are completed during the first visit — no waiting for parts to be ordered and shipped.
We stock LED modules across multiple color temperatures (3000K to 6500K) and match replacement modules to your existing sign. No patchwork appearance — your repaired sign looks uniform and professional.
Water damage is the number one killer of LED signs in the Northeast. We do not just fix the damage — we upgrade seals, gaskets, and drainage to prevent recurrence. Our repairs include a waterproofing assessment.
Every LED repair meets current NEC, NYC DOB, and NJ electrical codes. Our licensed electricians ensure your sign is not only working but fully compliant — protecting you from violations and liability.
When repairing older LED signs, we assess whether newer, more efficient modules could reduce your energy costs. Many clients save 20-40% on electricity after upgrading to current-generation LED technology.
Still running fluorescent tubes in your light boxes? We retrofit them to LED — brighter, more uniform light that uses 50-70% less energy and lasts 3-5 times longer. Same sign, dramatically better performance.

LED & Lighted Sign Issues We Fix
Individual LED modules burn out over time, creating dark spots or dead sections in your sign. This is the most common LED sign issue and usually the simplest to fix — if you have the right replacement modules.
LED drivers convert AC power to the DC current LEDs need. When drivers fail, entire zones of your sign go dark. Power surges, heat buildup, and water ingress are the most common causes of driver failure.
Cracked seals, aging gaskets, and damaged housings allow moisture inside your sign. Water corrodes LED modules, shorts wiring, and destroys drivers. The damage often spreads before symptoms appear externally.
LED modules from different batches or manufacturers can have slightly different color temperatures. When you replace some modules but not others, the mismatch becomes visible — some sections appear warmer or cooler.
LED flickering is usually caused by a failing driver, loose wiring connections, or voltage fluctuation. Unlike neon flicker, LED flicker often indicates an electrical problem that will worsen quickly.
Outdoor exposure causes wire insulation to crack, connections to corrode, and junction boxes to deteriorate. Poor original wiring or rodent damage compounds the problem.
Lighted Sign Repair in NY
The moment a lighted sign breaks down, it can cause problems for your business. That is why Metro Sign Services offers many services within 24 hours of receiving a customer’s phone call. We know that the longer you need to wait for your sign to be fixed, the more your company will suffer.
Once our technician makes their initial assessment, they’ll tell you about the problem and walk you through the solution. If they find that the sign is too damaged to be fixed, don’t worry. We also employ a team of designers who can create a new sign for you and have it installed. They can even design a brand new version if you’ve decided it’s time for something different.
Should You Repair or Replace Your LED & Lighted Signs?
When to Repair Your LED Sign
- Individual LED modules have failed while most still work
- Driver or power supply is the isolated issue
- Sign is less than 10 years old
- Water ingress is localized to one section
- Dimming is uneven but the majority of modules are fixable
- Wiring issue is the sole problem — components are sound
When to Replace Your LED Sign
- Majority of LED modules are failing across the sign
- LED technology is outdated and replacement parts are unavailable
- Sign is 15+ years old with degraded output
- Sign face is severely cracked, warped, or UV-damaged
- Color shift has affected the entire sign uniformly

Not sure? That is what the free assessment is for.
Our technician will inspect your sign and give you an honest recommendation — repair or replace — with a detailed quote for either option.
