An LED screen's lifetime depends on operating hours, brightness setting, heat, dust, humidity and power quality. Single LED or module faults during the screen's life are normal and are fixed by replacing the module. Front-service modules can be swapped without removing the screen from the wall. Warranty and service terms are set out in the written quote.
Short answer: An LED screen's lifetime depends on operating hours, brightness setting, heat, dust, humidity and power quality. Single LED or module faults during the screen's life are normal and are fixed by replacing the module; front-service modules can be swapped without removing the screen from the wall.

Daily operating hours, brightness set higher than needed, heat and ventilation inside the cabinet, dust and humidity, and voltage fluctuations matter most. Matching brightness to the environment, switching off at night and using an earthed, protected power line extend lifetime.
Indoors, dust the surface with a dry soft brush, check fans and vents and look for loose cables and connectors. Outdoors, also check seals and waterproofing, cabinet connections and power supplies at each change of season. The maintenance plan and scope are given in writing in the service quote.
A single dark LED (dead pixel) usually comes from impact, moisture or solder fatigue. A module going fully or partly dark is usually a module, cable or power supply fault. The fix is to replace the module with a spare from the same production batch and recalibrate if needed.
Modules from different batches can differ in colour and brightness, so it is wise to set aside spare modules and power supplies from the same batch at installation. The quantity is set in the quote by screen size.
In GOB (Glue on Board) modules the LEDs are sealed under a clear coating that protects them from knocks during transport, installation and cleaning, reducing dead-pixel risk where the screen is within reach.
We offer on-site inspection, fault diagnosis, spare parts, calibration, module and power-supply replacement and planned maintenance, and also assess screens of other brands. Warranty scope and terms are set out in the written quote.
