From emergency outage response to annual preventive maintenance contracts, we keep your display investment running at full performance.
Video walls are mission-critical assets. Whether a single pixel module has failed in your hotel lobby or your control room array has lost signal integrity, our technicians arrive with a stocked service van — carrying common LED modules, power supply units, signal processors, and calibration tools — to minimize downtime on-site.
We service all major manufacturers including Samsung, LG, Absen, Leyard, Unilumin, Daktronics, Barco, Christie, and Planar — covering fine-pitch LED, narrow-bezel LCD, rear-projection cube, Micro-LED, and OLED display technologies.
Diagnostic Inspection
Full electrical, thermal, and signal-path audit using spectroradiometers, thermal cameras, and EDID analyzers to pinpoint failure root cause.
Panel & Module Replacement
On-site swap of failed LED modules, pixel cabinets, or LCD panels with color-matched units — re-calibrated to the existing array.
Processor & Firmware Updates
Video wall controller and scaler firmware upgrades, EDID reprogramming, and HDCP compliance verification across all connected sources.
Preventive Maintenance Plans
Scheduled quarterly or bi-annual visits covering cleaning, thermal check, brightness recalibration, and firmware review to prevent failures before they occur.
Common Video Wall Problems We Resolve
Our field technicians diagnose and repair the full range of display failures encountered across LED, LCD, and rear-projection systems in commercial environments.
Dead or Stuck Pixels & Dark Spots
Localized LED module failure or LCD backlight degradation. We isolate and replace the affected module with a color-matched unit and recalibrate.
Color Shift & Brightness Inconsistency
Panel aging causes visible banding between tiles. We use hardware LUT profiling and spectroradiometer matching to restore uniformity across the entire array.
Signal Loss or No-Image Faults
HDMI, DisplayPort, or fiber signal interruptions caused by failed transceivers, damaged cables, or controller board failure. Full signal-path tracing and repair.
Overheating & Thermal Shutdowns
Blocked ventilation, failed cooling fans, or high-ambient-temperature environments. Thermal imaging audit, fan replacement, and airflow remediation.
Power Supply Failures
Failed PSUs cause entire panel rows or columns to go dark. We carry common power supply units for same-visit replacement on major LED and LCD platforms.
Control System Communication Errors
RS-232, IP, or Crestron/Extron command failures leaving displays unresponsive to room control. Driver updates, network reconfiguration, and control processor repair.
Image Tearing & Refresh Artifacts
Sync issues between video wall processor and source content. Frame rate matching, scaler reconfiguration, and processor firmware patching.
Physical Panel & Bezel Damage
Cracked LCD panels, dented LED cabinets, or misaligned bezel frames from impact or seismic activity. Structural realignment and panel replacement.
Maintenance Plan Tiers
Structured service agreements designed to match the operational requirements of your facility — from single-screen retail installs to 24/7 mission-critical control rooms.

Display Technologies & Brands We Service
Our technicians are factory-trained or certified on platforms from every major commercial display manufacturer deployed in Silicon Valley facilities.
Our Repair Process — Dispatch to Sign-Off
Every service call follows a documented workflow to ensure accurate diagnosis, transparent pricing, and a verified return to full operation before our technician leaves site.
Service Request & Remote Triage
Contact our service desk by phone or email. A technician will gather symptom details and — where remote access is available — perform preliminary diagnostics before dispatching on-site, reducing resolution time.
On-Site Diagnostic Assessment
Our technician arrives with a fully stocked service van including thermal camera, spectroradiometer, EDID analyzer, and common replacement parts. A written diagnosis with repair scope and cost estimate is delivered before any repair work begins.
Component Repair or Replacement
Approved repairs are completed on-site wherever possible. Failed LED modules, power supplies, control cards, and signal processors are swapped with tested replacements sourced directly from OEM suppliers or our certified parts inventory.
Recalibration & Verification
Following any panel or module replacement, we perform a full color and brightness recalibration using our CR-100 spectroradiometer to match the repaired area to the rest of the array. A signed service report documents all work completed and parts installed.
12-Month Parts & Labor Warranty
All repair work is backed by a 12-month warranty covering parts supplied and labor performed. Preventive maintenance plan clients receive extended coverage and priority scheduling for any subsequent service needs.
