Arcade game machine monitors, especially older CRT models, are prone to several issues over time due to prolonged use and aging components. Here are the most common problems:

1. Screen Burn-In: Static images displayed for long periods can permanently "burn" into the phosphor coating, leaving ghostly remnants.

2. Flickering or Rolling Images: Caused by failing capacitors, sync issues, or power supply instability.

3. Color Degradation: Over time, the CRT's phosphors weaken, leading to dull or incorrect colors.

4. Geometry Distortion: Warped or misaligned images result from worn-out deflection coils or magnetized components.

5. Dead Pixels or Lines: Physical damage or failing circuitry can cause black lines or unresponsive sections.

Regular maintenance, such as adjusting the flyback transformer or replacing capacitors, can extend monitor life. For severe burn-in or tube wear, replacement may be the only solution. Understanding these issues helps preserve classic arcade gaming experiences.
