Customer question: What can a quality inspection service verify before I buy or ship a used screen?
English explanation
A quality inspection service should combine documentation, visual, mechanical, electrical and display testing. It begins with inventory: cabinet count, model, pitch, dimensions, serials, receiving cards, power supplies, cables, flight cases and spares. It then records the condition of frames, locks, doors, connectors, seals, corrosion, water marks and repair history. Display testing should include full white, black, red, green, blue, gray scale, gradients, grid, text and motion. The report should identify dead pixels, bright pixels, colour cast, row/column defects, flicker, ghosting, low-gray issues and cabinet-to-cabinet uniformity. Tests should be performed under a stated brightness, content, viewing distance and environment, with both cold-start and stable-operation observations when relevant. Control inspection checks the controller, sending device, receiving-card model, firmware, RCFGX/configuration backup and port map. Electrical and internal checks must be performed by qualified personnel with power isolated where required. The final report classifies items as pass, limited use, repair required, information pending or rejection risk.
Service boundary
Inspection records current evidence; they do not create a new manufacturer warranty or guarantee future performance under an untested site condition. —
