Use this checklist whether or not LiveInSmart maintains your wall. It is the same schedule our engineers work to, written so a facilities team can run the routine items in-house and know precisely when to call a specialist.
Run a weekly visual check for dead pixels and colour patches, a monthly surface and filter clean, a quarterly module diagnostic with connector inspection and thermal check, and an annual recalibration plus health audit. Following this schedule typically prevents the two most expensive failure modes — thermal lumen decay and power-supply failure.
Weekly — Facilities Team, 10 Minutes
A quick pass while the wall is running. Log anything you find with a photograph and the cabinet reference so trends are visible over time.
Full-white and full-colour test frames — look for dead pixels, dim modules and colour patches
Check for flicker or intermittent rows, which usually indicates a loose ribbon or hub-card connector
Confirm the content player is on schedule and the correct playlist is running
Listen for fan noise change and feel for hot spots at the base of the wall
Verify the wall is being driven at the agreed brightness, not left at 100%
Monthly and Quarterly Tasks
Monthly work is largely cleaning and airflow. Quarterly work needs test equipment and a controller login, and is where an AMC engineer earns the contract.

Why it matters
Monthly
Soft-cloth surface clean (COB/GOB) or dry dusting (SMD)

Dust reduces contrast and traps heat
Monthly
Rear plenum and fan-filter cleaning

Airflow loss raises junction temperature
Quarterly
Module-by-module brightness and pixel scan

Quarterly
Connector, ribbon and hub-card inspection

Thermal cycling loosens connections

Symptom to first likely cause. Anything involving opening cabinets, controller configuration or power work should go to a qualified engineer.
Common LED wall symptoms and first checks
Symptom
Most likely cause
First action
One black cabinet
Power supply or power cable
Check feed and PSU LED; swap known-good cable
One black module
Failed module or hub connection
Reseat ribbon; hot-swap module from spares
Horizontal dead rows
Loose ribbon / driver IC
Reseat connector; replace module if persistent
Whole wall black, controller on
Sending-card signal or source
Verify source output and sending-card input
Colour patch across cabinets
Calibration drift or mismatched module batch
Recalibrate; if new module, apply batch correction
Flicker on camera only
Refresh rate too low
Raise refresh in controller to ≥ 3,840 Hz
Spares You Should Actually Hold
Every wall we hand over ships with a recommended spares kit sized to the installation. Holding spares locally is the difference between a 30-minute fix and a six-week import wait.
2–3% of total modules, from the same production batch as the wall
One power supply and one receiving card per 20 cabinets
One spare sending card for any control-room or broadcast wall
Labelled spare ribbon cables and data cables
Stored in a dry, dust-free cupboard — not on top of the rack
Who Engineered This Page — Experience, Expertise & Accountability
LiveInSmart Technologies is a commercial-AV and LED display system integrator, not a box reseller. Our own engineers run the site survey, structural and thermal calculation, pixel-pitch sizing, cabinet installation, receiving-card mapping, colour calibration and the AMC that follows. The guidance on this page is written from installations we commissioned and maintain across Telangana and Andhra Pradesh — indoor fine-pitch boardroom walls, high-brightness outdoor façades, 24×7 control rooms, auditorium stages and retail signage.
In-house AV engineering team — survey, structural drawings, load, thermal and power calculations
Genuine India-warranty cabinets with GST invoice, 3-year LiveInSmart installation warranty and structured AMC
Brand-agnostic specification across Unilumin, Absen, Hikvision, Samsung, Maxhub and Aaztec — chosen against your budget and redundancy needs, not a sales target
Two experience centres — Hyderabad (Ameerpet) and Vijayawada — with live LED walls you can audition before you buy
Get a Costed Design From an LED Engineer
Send us the space dimensions, closest viewing distance, ambient light level and the content you will run (dashboards, video, live camera, signage). Within two working days you get a designed configuration — pixel pitch, cabinet layout, controller, power and redundancy — with a line-item BOQ for LED wall maintenance, not a one-line price.

COB and GOB surfaces can be wiped with a soft, dry or barely damp microfibre cloth. SMD walls should only be dusted gently with a soft brush or low-pressure air, never wiped hard, because the exposed lamps can be knocked off. Never use solvents or spray liquid at the wall.
How often should an LED wall be serviced?+
Quarterly preventive service for commercial walls, and quarterly plus remote monitoring for 24×7 control rooms. Monthly cleaning can be done in-house by facilities staff following the schedule on this page.
Why has part of my LED wall changed colour?+
Usually calibration drift or a replacement module from a different production batch. A recalibration with batch correction resolves it. If the patch is warm to the touch, check airflow first — thermal stress accelerates colour shift.
Do you service LED walls you did not install?+
Yes, multi-brand. We begin with a paid health audit covering pixel loss, brightness uniformity, controller configuration, power loading and spares availability, then propose either a corrective visit or an ongoing AMC.
