Arcade machines are beloved for their nostalgic charm and engaging gameplay, but like any electronic device, they can experience power supply issues. The most common problems include blown fuses, overheating power supplies, voltage fluctuations, and faulty capacitors.

1. Blown Fuses: Often caused by power surges or short circuits. Replace the fuse with one of the correct rating and check for underlying issues.

2. Overheating Power Supplies: Dust buildup or poor ventilation can cause overheating. Clean the power supply and ensure proper airflow.

3. Voltage Fluctuations: Use a multimeter to test voltage outputs. If inconsistent, the power supply may need replacement.

4. Faulty Capacitors: Swollen or leaking capacitors disrupt power flow. Replace them with new, high-quality capacitors.

Regular maintenance and timely repairs can extend the lifespan of your arcade machine. If unsure, consult a professional technician for complex issues.
