Commercial Sign Repair in Los Angeles
Business sign light repair across Los Angeles, CA.
A dark or half-lit sign tells customers you are closed, even when you are open. Burned-out LED sections, a dead power supply, or aging neon leave your storefront looking neglected after dark. Los Angeles Sign Company diagnoses, repairs, and relights business signs for storefronts, offices, and shopping centers across LA County.
Sign Lighting We Bring Back to Life
Most sign lighting problems come down to a handful of parts, and most can be fixed without replacing the whole sign. These are the repairs we handle most often for Los Angeles businesses.
Channel Letter Repair
Individual lit letters are the most common storefront sign, and the most common to lose a section. We fix dead letters and dim spots in channel letters, front-lit or halo-lit.
- Dead or dim sections
- Failed LED modules
- Face-lit & halo-lit
Neon Sign Repair
Vintage and custom neon signs can be repaired when a tube cracks or a section goes dark, or converted to LED-faux-neon if you would rather stop the upkeep.
- Cracked or leaking tubes
- Dark or flickering sections
- Repair or LED conversion
LED Retrofit & Conversion
Old neon and fluorescent lighting can be converted to LED for a brighter, lower-maintenance sign that uses less power. Often the smartest fix on an aging sign.
- Neon & fluorescent to LED
- Brighter, more even light
- Lower energy & upkeep
Cabinet & Lightbox Sign Repair
Cabinet and lightbox signs light from within, so a single failed lamp or driver can darken the whole face. We relight the box and replace worn or yellowed panels.
- Dark or patchy faces
- Lamp, LED & driver swap
- Cracked or faded panels
Power Supply, Transformer & Ballast
When a whole sign goes dark, the cause is usually the power side. We replace failed LED drivers, neon transformers, and fluorescent ballasts with matched, code-compliant parts.
- Sign fully out or buzzing
- LED drivers & supplies
- Transformers & ballasts
Pylon, Monument & Storefront Relighting
Tall pylon signs, monument signs, and full storefront sets need a lift and a plan. We relight the whole display and get every element reading bright again at night.
- Pylon & monument signs
- Multi-tenant panels
- Full storefront relighting

Fix What Failed, or Convert to LED
An older sign gives you a choice: fix the part that failed, or convert the whole sign to LED while the crew is already up there. We price both and tell you honestly which is the better spend, no upsell.
Fix what failed
Best when the sign is in good shape and one part gave out.
- Fastest way to get the sign lit again
- Lowest cost when only one part failed
- Replace the failed module, lamp, tube, or driver
- Keeps your existing sign exactly as it is
Convert to LED
Best on aging neon or fluorescent signs that keep failing.
- Brighter and more even light
- Uses far less power and lasts years longer
- Fewer service calls and a lower power bill
- Often cheaper over time than fixing it twice

What Usually Fails, and How We Fix It
Sign lighting problems almost always trace back to one of these parts. Here is what tends to go, and the repair we make.
LED modules
Dead or dim sections, uneven color, water damage
Neon tubing
Cracked tube, gas leak, dark or flickering sections
Fluorescent lamps
Flicker, blackened ends, dead lamps in a cabinet
Power supplies & drivers
Sign fully out, buzzing, or tripping the breaker
Transformers & ballasts
Neon not firing, humming, slow or no start
Wiring, sockets & timers
Shorts, corrosion, sign on all day or never on
LED
The standard for modern signs. We replace failed modules and drivers, and retrofit older signs.
Neon
Classic glass-tube lighting. We repair dark tubes and transformers, or convert to LED.

Power & controls
