2-Year Free Warranty
Comprehensive factory-backed coverage from the date of shipment — no hidden conditions, no service fees. Every component is protected so you can deploy with confidence.
LED Modules
Full replacement for pixel failures, dead zones, or colour shift caused by manufacturing defects.
Power Supplies
Covers output instability, component burnout, and premature capacity loss under normal operating conditions.
Control Cards & Receivers
Sending and receiving cards covered against signal loss, firmware corruption, and hardware faults.
Structural Cabinets
Welding seams, locking mechanisms, and panel alignment covered against manufacturing-related structural issues.
Replacement Parts
Defective units are shipped at no charge; return logistics assistance available for verified warranty claims.
On-Site Service
Dispatch can be arranged for complex failures in select markets where local engineers are available.
Remote Technical Support
Our engineers connect directly to your system via TeamViewer or AnyDesk to diagnose and resolve issues in real time — no travel required, no delays waiting for a site visit.
Screen Calibration
Full display calibration including brightness uniformity, colour temperature alignment, and white balance correction.
Colour Uniformity Correction
Module-level colour mapping adjustments to eliminate visible seams, hot spots, or tonal inconsistencies across panels.
Brightness & Gamma Tuning
Precision tuning of brightness curves and gamma profiles for optimal visibility in ambient lighting conditions.
Control Software Configuration
Setup and troubleshooting of Nova Star, Linsn, or Colorlight control systems, including input mapping and scheduling.
Firmware Updates
Remote firmware flashing for sending cards, receiving cards, and display processors to resolve bugs and improve stability.
Fault Diagnosis
Systematic remote diagnostics to isolate signal chain issues, identify failing modules, and guide replacement procedures.
Frequently Asked Questions
Quick answers to common technical and maintenance questions about your LED display.
Our comprehensive 2-year warranty covers all manufacturing defects, component failures, and hardware malfunctions. This includes LED modules, power supplies, control cards, and structural cabinets. The warranty is valid from the date of shipment and covers replacement parts and remote technical guidance. On-site service may be arranged in select markets.
Remote calibration can be requested through your account manager or by contacting our technical support team at jim@visualleds.com. Our engineers will schedule a session, connect to your display via TeamViewer or AnyDesk, and perform color uniformity correction, brightness adjustment, and gamma tuning -- all without requiring an on-site visit.
The most common causes include: power supply instability or voltage spikes, moisture ingress (inadequate sealing), physical impact during transport or installation, and overheating due to blocked ventilation. Regular inspection of power connections, cleaning of cooling fans, and ensuring proper IP rating compliance significantly reduce failure rates.
For outdoor displays, we recommend quarterly visual inspections and annual deep cleaning. Indoor displays require less frequent maintenance -- semi-annual checks are typically sufficient. Key maintenance tasks include: cleaning module surfaces, inspecting cable connections, testing backup power systems, and verifying control system firmware is up to date.
In many cases, yes -- but compatibility depends on the cabinet generation, control system version, and pixel pitch. Displays manufactured after 2020 using standard 320×160 mm or 500×500 mm modules often support cross-generation upgrades. Contact our technical team with your display model number and we will confirm upgrade feasibility and provide a compatibility report.
