Customer question: The LEDs work, but how do I know the cabinets are mechanically safe to install?
English explanation
Inspect the cabinet as a structural and service product, not only as a display surface. Check frame flatness, corners, door panels, locks, handles, hanging points, support feet, alignment pins, screws and signs of deformation. For rental cabinets, operate every lock and confirm that it reaches the fully locked position. A narrow seam does not prove that the lock is engaged. Inspect power and signal connectors for cracks, looseness, corrosion, bent contacts and damaged locking shells. Check whether cables are pulled by their connectors or supported correctly. For outdoor cabinets, review gaskets, doors, drainage and water marks. For front-service cabinets, confirm that the specified service tool can reach the module without damaging the LED surface. For suspended systems, check the approved lifting points and secondary safety equipment; never infer load capacity from a photograph. Number each cabinet and photograph the rear, connectors and mechanical condition. A used cabinet with a cosmetic scratch may be acceptable, while a slightly bent frame or damaged lock can create alignment and safety problems across an entire wall. If the cabinet has been repaired, ask what was changed and whether the replacement parts match the system.
Service boundary
Structural, lifting and building-load approval must be completed by qualified local professionals. A display inspection can identify visible risks but cannot replace structural certification. —
