Screen burn-in is a common issue in arcade machines, especially those using CRT monitors. The most frequent causes include prolonged display of static images, high brightness settings, and aging phosphor layers. Classic arcade games with fixed HUDs or score displays are particularly prone to this problem.

To prevent screen burn-in, consider these solutions:

1. Use screen savers or attract modes when the machine is idle.

2. Rotate games regularly to vary on-screen content.

3. Adjust brightness and contrast to optimal levels.

4. Implement automatic power-off features during extended inactivity.

5. For severe cases, consider monitor rejuvenation or replacement.

Modern LCD alternatives eliminate burn-in risks but may lack the authentic CRT feel prized by collectors. Proper maintenance remains key to preserving vintage arcade machines.
