Professional service for LED modules and components
At Trefyr, we provide specialized LED repair services covering everything from individual modules to large LED video wall systems. Our focus is to restore full functionality and image quality to factory standards with speed, accuracy, and care.
All repairs are performed in-house at our workshop in Linköping, using professional tools and testing equipment to ensure precise and reliable results.
Thanks to our experience, technical expertise, and fast access to replacement parts, we can service both standard and custom LED solutions regardless of brand, model, or complexity. Whether you are dealing with dead pixels, color issues, power failures, or damaged modules, we make sure your LED display is up and running again as quickly as possible.
We perform detailed repairs on LED modules to restore optimal performance and image quality. This includes replacing SMD pixels, repairing damaged PCB traces, and precision soldering of components. Every module is thoroughly tested and calibrated to ensure consistent brightness and accurate color balance before being returned.
We diagnose and repair control cards, hub cards, and receiver cards. This may involve replacing IC components, restoring damaged traces, and adjusting or updating firmware. The goal is to restore proper synchronization, signal strength, and reliable data transmission across the entire display.
We troubleshoot, replace, and test power supplies to ensure stable and safe operation. Our technician checks wiring, fuses, and components that commonly cause voltage issues or overheating. After repair, the PSU is load tested to verify reliability and consistent power distribution.
At Trefyr, we specialize in professional diagnostics and repair of LED screens for companies in the event, AV, and rental industry.

All work is carried out in-house at our workshop in Linköping, which gives us full control over every step of the process, from intake to final testing. This also means shorter turnaround times and consistent quality.
