When purchasing an LCD 비디오 벽, thevideo wall warranty policy is a critical factor that determines long‑term total cost of ownership. Qtenboard offers a minimum 1‑3 year comprehensive warranty on the complete system, with customisable extensions available. Coverage periods vary by component: LCD panels typically carry a 3‑5 year warranty, while driver boards and video controllers are usually covered for 1‑3 years. The warranty includes manufacturing defects, natural failures under normal commercial use, and display anomalies caused by factory calibration drift.
The following situations are generally not covered and should be clarified before signing any contract:
💡 B‑2‑B Procurement Checklist: Before signing, confirm these points – Is the warranty parts‑only or does it include remote technical support? (Qtenboard provides remote diagnostics and parts replacement with fast shipping; no on‑site labour is included.) When does the warranty period start – from the delivery date or from the installation acceptance date? Is an extended warranty available? Qtenboard offers remote support and system upgrades, ensuring rapid response without the need for on‑site visits.
A national broadcasting studio in the UK required a visual infrastructure upgrade with exceptional display performance, operational stability, and future expandability. Qtenboard delivered a complete LCD video wall solution including display units, control systems, and structural design support. The studio environment demanded 24/7 continuous operation; Qtenboard’s video wall uses long‑life backlighting, advanced thermal management, and industrial‑grade components to ensure reliability and minimise downtime. After commissioning, Qtenboard provides continuous remote technical support and system upgrades, keeping the studio running smoothly for years.
Video wall spare parts supply is one of the most overlooked risks 3‑5 years after project deployment. Once the original model is discontinued, a single faulty panel can render the entire wall unusable if replacements are unavailable. A reliable supplier must have a robust parts availability programme.
Panel / bezel matching is essential – replacement panels must match the original bezel width (3.5mm, 1.8mm, 0.88mm, 1.7mm, or 0mm seamless) and the same batch colour calibration parameters; otherwise, “yin‑yang” colour differences will appear. → Bezel Comparison Guide
📌 B‑2‑B Procurement Advice: Include spare parts supply lead times, end‑of‑life ordering terms, and price‑lock mechanisms in the contract during the tender phase. Don’t wait until after delivery to discover there’s no safety net.
A major tunnel project in Vietnam needed a highly reliable LCD video wall for real‑time surveillance, traffic management, and emergency coordination. Qtenboard designed a custom video wall tailored to the control room layout and tunnel monitoring requirements, supporting multi‑source video stitching and 24/7 uninterrupted operation. Long‑term stability was paramount – every panel underwent rigorous burn‑in and reliability testing. Qtenboard established a dedicated spare parts inventory for this project, ensuring that critical components could be replaced quickly throughout the 5‑year operational lifecycle, safeguarding Vietnam’s intelligent transport infrastructure.
Video wall remote monitoring transforms after‑sales service from reactive fire‑fighting to proactive prevention. Qtenboard’s cloud‑based system provides 7×24 real‑time status tracking, including panel temperature, signal integrity, brightness degradation trends, and running hours (average panel life 60,000 hours).
Control room applications – remote monitoring delivers maximum benefit in 24/7 control rooms such as CCTV surveillance, traffic command centres, airports, and smart city projects, where continuous operation and system stability are non‑negotiable. → Control Room Setup 5‑Step Guide
A large entertainment complex in Bangkok deployed Qtenboard’s 4×7 (28 units) 55‑inch 0.88mm ultra‑narrow‑bezel LCD panels in its data command centre. The centre handles 2,000‑10,000 visitors daily, monitoring ticketing, crowd density, and venue occupancy in real time. Qtenboard’s remote monitoring system continuously tracks panel health, ensuring 24/7 stability even in Southeast Asia’s hot and humid climate. After going live, decision‑making efficiency improved by over 40%. During a 15,000‑person weekend concert, the operator used real‑time data to identify congestion points and redirect foot traffic, preventing safety incidents. The customer rated the clarity and reliability 9.5/10.
Video wall troubleshooting is an essential skill for on‑site maintenance teams. The following self‑checklist helps you identify common issues within 10 minutes, clearly distinguishing between problems you can solve yourself and those that require technical support.
Three‑step self‑check: ① Check all cables (HDMI / DP / Ethernet) → ② Verify the signal box (power indicator, input source selection) → ③ Test the source device (is it outputting correctly?).
Determine whether it’s a single‑panel fault or a calibration drift affecting the whole wall. For a single panel, inspect its connection and the panel itself. For overall colour shift, check the signal source and controller configuration.
Three‑step diagnosis: ① Check main power input → ② Check each unit’s power LED status → ③ Verify the RS232 control signal.
Incorrect controller architecture selection is a common root cause of synchronisation problems; different projects require different controller types. → Controller Comparison Guide
| Issue Type | Can self‑check (10 min) | Requires support / parts |
|---|---|---|
| Signal loss | ✅ Check cables, signal box, source | ❌ If above steps fail |
| Single panel flicker | ✅ Check the unit’s connection | ❌ If cable replacement fails → panel/driver fault |
| Entire wall black | ✅ Check main power and unit LEDs | ❌ If power is normal → controller fault |
| Colour / calibration drift | ✅ Check source settings | ❌ If settings are correct → professional calibration needed |
| Controller desync | ❌ Cannot self‑check | ✅ Contact technical support immediately |

A luxury club in Indonesia installed a custom Qtenboard LCD video wall as its central visual attraction. The system needed to operate flawlessly under mixed lighting conditions for long hours, with smooth content switching and stable performance. Qtenboard delivered ultra‑narrow‑bezel panels with Full HD / 4K resolution and high brightness. Every panel underwent strict quality control and burn‑in testing to ensure stability during continuous night‑time operation. After delivery, Qtenboard provides ongoing remote technical support and system upgrades, ensuring the club’s visual output remains reliable through its busy nightlife schedule.
Hardware specifications define the project’s starting point; after‑sales support defines the total cost of ownership over its lifetime. → Project Cost Breakdown & 5‑Year TCO . “Cheaper panel + hidden costs = a much larger final bill.”
Industry standard is 1‑3 years for the complete system and 3‑5 years for LCD panels. Qtenboard offers a minimum 1‑3 year warranty with custom extensions available. Always confirm whether the warranty covers parts replacement and remote support (Qtenboard does not include on‑site labour).
A reliable supplier maintains safety stock and provides an end‑of‑life notification (12 months before discontinuation, with a 6‑month final order window). These terms should be included in the initial contract.
Yes – Qtenboard’s cloud platform monitors temperature, signal status, brightness trends, and operating hours 24/7. Anomalies trigger early alerts, enabling proactive intervention before a failure occurs.
Follow the three‑step self‑check: ① cables, ② signal box, ③ source device. If none resolve the issue, contact technical support.
Yes – unauthorised controller replacements may void the warranty (classified as third‑party modification). Confirm controller selection during the design phase.
Qtenboard provides 24/7 online support via ticketing, phone, and email. Response SLAs are defined for each region.
