Pixel Repair Specialists
Dead, stuck, or dim pixels? Our engineers replace individual LEDs under high-powered microscopes — color and brightness matched — on modules from 1.2 mm pixel pitch to the largest in the market.

“They’ve done an outstanding job for us for over two years now, and their service is perfection to say the least.”Tod P. · North Georgia LED
Quick Check
The pattern on your screen tells us a lot. Here’s how to tell a pixel failure from an IC or module-level issue.
Individual dots that stay dark, stuck on one color, or dimmer than the rest. This is a pixel-level repair.
An entire line of pixels goes dark or shows the wrong color. That usually points to a failed driver or scan IC.
Large dark areas, flickering, or a module that won’t display at all needs a full module-level diagnosis.
Superior Pixel Replacement
Replacing a pixel is only half the job. If the new LED doesn’t match its neighbors, your audience will see the repair.
LEDs vary in color and brightness from one production batch to the next. A quick-fix repair drops in whatever LED is on hand — and leaves a pixel that glows brighter, dimmer, or a slightly different color than the rest of the wall.
Our engineers select replacement LEDs to match the surrounding pixels, then verify color and brightness under test before QC. The goal is simple: once your module is back in the wall, no one should be able to tell which pixel was repaired.
Our Pixel Repair Process
1
Every dead, stuck, or dim pixel is located and logged.
2
We check the LED, pads, and solder joints up close.
3
Controlled technique that protects the pads and board.
4
A matched LED is placed and precision-soldered.
5
Brightness and color verified against neighbors.
6
Two-stage QC, video proof, and a repair log report.
Know the Cause
Most pixel failures are preventable. Understanding the cause helps you protect your investment between repairs.
01
Bumps during load-in, load-out, and shipping — especially at corners and edges — crack LEDs and lift pads.
02
Humidity, condensation, and outdoor exposure corrode solder joints and contacts over time.
03
Static from handling can damage LEDs and driver components without any visible sign.
04
Heat cycling, long operating hours, and manufacturing defects weaken LEDs until they fail.
Pro Tips
Next-Level Pixel Repair

FAQ
Common questions about dead pixel repair, pixel pitch, and color matching.
Pixel pitch is the distance between the centers of two adjacent pixels on an LED display, measured in millimeters. It directly affects the display’s resolution and ideal viewing distance — the smaller the pitch, the finer the detail and the more precise the repair work needs to be.
Our engineers repair LED modules from 1.2 mm pixel pitch to the largest pitches on the market, regardless of brand.
Dead pixels are usually caused by physical impact during handling or shipping, moisture and corrosion, electrostatic discharge, heat and age, or manufacturing defects. They appear as dark, unlit spots on the screen.
A dead pixel stays completely unlit. A stuck pixel stays fixed on a single color, such as red, green, or blue. Both are typically repaired at the pixel level after microscope inspection identifies the cause.
That’s our goal on every repair. We select replacement LEDs to match the surrounding pixels and verify color and brightness under test before QC, so the repaired pixel blends in with the rest of the wall.
Pixel repair is often far more cost-effective than replacing a module, especially when replacements are expensive or hard to source. After diagnostics, we’ll give you an honest recommendation based on the extent of the damage.
Yes. Corner and edge damage from impact is one of the most common issues we repair. When the impact also damaged pads or traces, the repair may include PCB reconstruction.
For larger or permanently installed displays, our technicians may be able to travel to your location. Availability depends on schedule, location, module quantity, and work conditions.

Serving Clients Nationwide
José de Jesús “Chuy” Martínez is the founder and CEO of 725co. LED Repair Professionals, with more than two decades of hands-on electronics experience and over a decade specializing in professional LED display technology. His expertise reaches far beyond the repair bench, encompassing live-event production, LED video wall assembly, on-site technical support, and permanent display installations.
His technical foundation began in León, Guanajuato, Mexico, where he learned electronics alongside his father, an electronics repair technician. From repairing cassette players for classmates to developing advanced diagnostic skills on computers and electronic equipment, Chuy built a reputation for solving difficult technical problems. In 2008, he established his first business, 777 Computer Repair, specializing in hands-on troubleshooting and component-level repairs.
In 2012, an invitation from his friend Luis brought him into the professional LED industry through Matrix Visual. Working from the beginning as an independent contractor under LED REPAIR TECHS, Chuy developed extensive field experience traveling to major productions, assembling LED video walls, diagnosing technical issues, and repairing displays during live shows—often under the time-sensitive demands of an active event.
Throughout his career, he has contributed to events and productions involving major audiovisual companies, including PRG, 4Wall, and Freeman, as well as numerous other industry providers. A notable example was his work installing and repairing LED screens for the live performance featured in Kevin Hart: What Now?, the 2016 concert film. His background also includes extensive experience with permanent LED display installations, giving him a broad understanding of display systems from installation through maintenance and repair.
As his responsibilities at Matrix Visual expanded, Chuy took charge of its repair operation, personally recruiting, training, and directing a growing team of technicians. His first recruit was his brother David. He incorporated LED REPAIR TECHS INC in 2018 and opened a dedicated repair facility in Garden Grove, California, in 2021, building on the professional relationships and technical reputation he had established across the industry.
In 2022, he introduced 725co as the company’s DBA in memory of David, whose birthday was July 25. Today, Chuy combines deep technical knowledge, extensive production experience, and entrepreneurial leadership to guide 725co with a focus on precision, reliability, and professional repair standards—while carrying forward the family legacy behind its name.
