LED screen replacement involves removing old or faulty screens/modules and installing new ones, typically done when repairs are no longer cost-effective (e.g., most modules are degraded) or when upgrading to newer technology (e.g., replacing a Full HD screen with a 4K one). It requires careful planning to minimize downtime and ensure compatibility with existing systems.

First, assessment determines if replacement is needed: if repair costs exceed 50% of a new screen’s price, or if the screen is outdated (e.g., can’t support 4K content), replacement is better. For modular screens, technicians may replace only faulty modules (e.g., replacing 10% of degraded modules) instead of the entire screen—saving costs.

Planning includes compatibility checks: new modules must match the old screen’s pixel pitch (e.g., replacing 2.5mm modules with 2.5mm ones) and voltage requirements to work with existing driver boards and power supplies. For full-screen replacement, technicians check if the new screen fits the existing frame/mounting structure—if not, they modify the structure (e.g., adjusting brackets for a larger screen) or install a new one.

Removal of the old screen is done safely: power is disconnected, cables are labeled (to avoid confusion during installation), and modules/driver boards are removed one by one—carefully storing reusable parts (e.g., control cards) if possible. For outdoor screens, structural safety is ensured—using cranes to remove large screens and checking the frame for damage before installing the new one.

Installation of the new screen follows the standard installation process: mounting modules, connecting cables, and testing. Post-installation, technicians calibrate colors and brightness to match the user’s needs (e.g., calibrating a broadcast studio screen to DCI-P3 standards) and train users on new features (e.g., a 4K screen’s enhanced content playback).

Replacement also involves disposing of old components properly: LED modules and driver boards contain electronic waste, so technicians work with certified recyclers to ensure compliance with environmental regulations (e.g., separating plastic casings from metal components). This reduces environmental impact while upgrading the screen to meet modern performance demands.
