Arcade machines are beloved for their nostalgic gameplay, but input device failures can ruin the experience. The most common causes include:

1. Worn-Out Joysticks: Heavy use leads to plastic fatigue, broken microswitches, or loose springs, causing erratic movements.

2. Faulty Buttons: Sticky or unresponsive buttons often result from dirt buildup, worn-out switches, or damaged wiring.

3. Loose Connections: Over time, wiring harnesses can disconnect or corrode, interrupting signal transmission.

4. Physical Damage: Impact or rough handling can bend components or crack circuit boards.

5. Dust and Debris: Accumulated grime interferes with mechanical parts, leading to poor performance.

Regular cleaning, proper handling, and timely repairs can extend the lifespan of arcade input devices. For persistent issues, professional servicing may be required.
