Arcade machines are beloved for their nostalgic charm and engaging gameplay, but like any electronic equipment, they are prone to technical failures. Here are the most common hardware issues encountered in arcade machines:

1. Power Supply Problems: Faulty power supplies can cause machines to fail to boot or randomly shut down. Overheating or aging capacitors are often the culprits.

2. Joystick and Button Malfunctions: Worn-out microswitches, loose connections, or debris buildup can make controls unresponsive or overly sensitive.

3. Monitor or Screen Issues: Flickering screens, color distortion, or complete failure may result from damaged CRT tubes, loose wiring, or failing video boards.

4. PCB (Printed Circuit Board) Failures: Corrosion, cold solder joints, or damaged chips can lead to game freezes, graphical glitches, or sound problems.

5. Coin Mechanism Errors: Jammed or misaligned coin slots, worn-out sensors, or electrical faults can prevent proper coin insertion and credit registration.

Regular maintenance, cleaning, and timely repairs can extend the lifespan of arcade machines. For complex issues, consulting a professional technician is recommended.
