Arcade machine monitors, especially older CRT models, often face several common issues due to age, wear, or environmental factors. Here are the most frequent problems and their solutions:

1. Screen Flickering or Rolling – This is usually caused by a faulty vertical or horizontal hold adjustment. Fix it by adjusting the monitor’s potentiometers or replacing the sync circuit components.

2. No Display or Blank Screen – Check the power supply, flyback transformer, or neck board for issues. A blown fuse or bad capacitor could be the culprit.

3. Color Problems (Faded or Tinted) – Degraded color guns or misaligned convergence strips may cause this. Recalibrate the RGB settings or replace the color transistors.

4. Burn-In or Ghost Images – Permanent phosphor damage from static images requires a tube replacement. Prevent it by using screen savers or reducing brightness.

5. Distorted Geometry – Wavy or stretched images often stem from failing capacitors. A cap kit replacement usually resolves this.

Regular maintenance and proper voltage adjustments can extend the life of arcade monitors. For complex repairs, consulting a professional is recommended.
