Arcade machine refurbishment is essential for preserving the functionality and aesthetics of classic arcade games. The most common refurbishment processes include:

1. Cabinet Repair and Restoration: Damaged or worn-out arcade cabinets are repaired, repainted, or re-laminated to restore their original appearance. This may involve replacing side panels, control panels, or artwork.

2. Monitor and Display Refurbishment: CRT or LCD screens are cleaned, recalibrated, or replaced to ensure crisp visuals. Capacitor replacement and tube rejuvenation are common for older CRT monitors.

3. Control Panel Overhaul: Worn-out joysticks, buttons, and wiring are replaced to improve gameplay responsiveness. Custom upgrades, such as adding LED lighting, are also popular.

4. PCB and Electronics Repair: Faulty circuit boards are repaired or replaced to fix game glitches or boot failures. This may involve soldering, cleaning corrosion, or swapping damaged components.

5. Cosmetic Upgrades: Side art, marquees, and bezels are often reprinted or replaced to enhance the machine's visual appeal.

6. Power Supply and Wiring Check: Aging power supplies and frayed wiring are inspected and replaced to prevent electrical hazards.

By following these refurbishment processes, arcade enthusiasts can breathe new life into vintage machines while maintaining their nostalgic charm.
