An LED display is a major investment. A well-maintained LED screen can last 10–15 years. A poorly maintained one may fail within 3–5 years — especially in Nepal’s challenging climate of monsoon humidity, dust, and temperature swings. Evolve Tech has serviced over 1,000 LED displays across Nepal.
1. Control Brightness Based on Ambient Light
Running outdoor LED displays at maximum brightness 24 hours a day dramatically shortens LED lifespan. We recommend: Daytime (6am–6pm): 80–100% | Evening (6pm–10pm): 50–70% | Late night (10pm–6am): 20–30% or auto-off. Most modern LED controllers (Novastar, Huidu) support automatic brightness scheduling.
2. Protect Against Nepal’s Monsoon Season (June–September)
Nepal’s monsoon brings 1,400–2,600mm of rain annually. Before monsoon season (May): check all cabinet seals and gaskets, inspect drainage holes, verify IP65 rating integrity, and check rear cable entry points for water ingress.
3. Clean the Screen Surface Regularly
Outdoor screens: monthly cleaning with soft microfiber cloth. Indoor screens: quarterly cleaning. Use: Dry microfiber cloth or isopropyl alcohol (70%) diluted with water. Never use abrasive materials, acetone, or high-pressure water jets.
4. Monitor and Control Cabinet Temperature
LED modules overheat when cooling fans fail, cabinet vents are blocked by dust, or ambient temperature exceeds 40°C. Signs of overheating: color shift, uneven brightness, random pixel failures. Check fan operation monthly and clean air vents with compressed air every 3–6 months.
5. Check Power Supply Units (PSUs) Every 6 Months
Power supply failures are the #1 cause of LED display downtime in Nepal. PSU lifespan is typically 5–7 years. Signs of a failing PSU: entire cabinet section going dark, flickering in one area, burning smell. Evolve Tech keeps common PSU models in stock for rapid replacement.
6. Protect Against Load-Shedding and Power Surges
Nepal’s power grid experiences voltage fluctuations and load-shedding. Install a Servo Voltage Stabilizer (SVS), use a UPS for controller hardware, install surge protection devices (SPDs) at the DB box, and properly ground the steel structure and cabinets.
7. Schedule Annual Professional Service
Annual professional inspection covers: full pixel-by-pixel dead pixel check, color calibration, structural inspection, electrical safety check, firmware updates, and internal component cleaning. Evolve Tech’s Annual Maintenance Contract (AMC) starts from NPR 25,000/year.
When to Call Evolve Tech for Emergency Service
Contact us immediately if you observe: more than 10 dead pixels per m², a full panel section not displaying, physical damage to cabinets, smoke or burning smell, or screen not responding to controller commands.
