Arcade machines, like any electronic equipment, require regular maintenance and occasional repairs. To diagnose issues accurately, technicians rely on specialized diagnostic tools. Here are the most common types of diagnostic tools used in arcade machine repairs:

1. Multimeters: Essential for measuring voltage, current, and resistance, multimeters help identify power supply issues or faulty wiring in arcade machines.

2. Logic Probes: These tools detect digital signals on printed circuit boards (PCBs), making them invaluable for troubleshooting logic-level problems in game boards.

3. PCB Testers: Designed specifically for arcade PCBs, these testers check for continuity, shorts, and component failures, ensuring the board functions correctly.

4. Oscilloscopes: Used to analyze signal waveforms, oscilloscopes help diagnose timing issues or signal distortions in arcade machine electronics.

5. ROM Burners and Testers: These tools verify and reprogram ROM chips, ensuring game software runs without glitches.

By using these diagnostic tools, technicians can efficiently pinpoint and resolve issues, keeping arcade machines in optimal condition for players to enjoy.
