This document introduces a laptop and desktop computer sales and repair center. It discusses common screen display problems like horizontal white lines or multi-colored vertical lines that can be caused by fiber dust accumulation blocking cooling air flow after a year of use. The center offers to fully disassemble, clean, and replace thermal paste to remove dust and restore devices to like-new condition, and can perform board-level repairs on any brand. Customers are urged to get devices serviced after a year of use or when warranties expire to prevent costly overheating failures.
