Arcade machines are beloved for their nostalgic charm and thrilling gameplay, but like any electronic device, they can suffer from power supply issues. Here are the most common problems you might encounter:

1. Blown Fuses: A frequent issue caused by power surges or short circuits. Replacing the fuse is simple, but recurring blows indicate deeper problems.

2. Failing Power Supply Unit (PSU): Over time, PSUs degrade, leading to inconsistent voltage output or complete failure. Symptoms include random shutdowns or screen flickering.

3. Loose or Corroded Connections: Dirty or loose wiring can disrupt power flow. Regular cleaning and tightening of connections can prevent this.

4. Voltage Fluctuations: Incorrect voltage settings or unstable power sources can damage components. Use a multimeter to check and adjust voltage levels.

5. Capacitor Failure: Aging capacitors may bulge or leak, causing power instability. Replacing them restores proper function.

6. Overheating: Poor ventilation or dust buildup can cause the PSU to overheat, leading to shutdowns. Ensure proper airflow and cleaning.

By identifying and addressing these issues early, you can keep your arcade machine running smoothly for years to come. Regular maintenance and proper power management are key to avoiding costly repairs.
