Sourcing authentic components for arcade machine repairs presents significant hurdles for collectors and technicians. The primary challenge stems from component obsolescence, as many original manufacturers ceased production decades ago. Locating functional CRT monitors, specialized joysticks, and original PCB boards requires extensive networking within niche communities and specialized salvage operations.

Supply chain limitations further complicate procurement, with few manufacturers producing dedicated replacement parts. This scarcity drives up prices, particularly for sought-after components like authentic coin mechanisms or vintage display panels. Verification part authenticity becomes crucial, as incompatible or modern replacements often fail to maintain the machine's original gameplay experience.

Geographic disparities in available inventory create additional obstacles, requiring international shipping for rare components. Technicians must also navigate compatibility issues between regional hardware versions and address physical wear on mechanical parts that lack modern equivalents. These collective challenges necessitate creative problem-solving and deep industry knowledge for successful arcade restoration projects.
