Arcade game machine displays are prone to several failure modes due to prolonged use, environmental factors, and aging components. The most common issues include:

1. CRT Monitor Degradation: Classic arcade games often use CRT monitors, which suffer from burn-in, color fading, and geometry distortion over time. Capacitor failures can also cause flickering or no display.

2. LCD Screen Defects: Modern arcades with LCD screens face dead pixels, backlight failure, and image retention. Poor-quality panels may develop lines or discoloration.

3. Power Supply Issues: Faulty power boards can lead to intermittent display problems or complete screen blackouts.

4. Connector and Cable Damage: Loose or corroded video cables and connectors result in signal loss, ghosting, or distorted images.

5. Environmental Damage: Exposure to moisture, heat, or physical impact can crack screens or damage internal circuits.

Regular maintenance and timely repairs can extend the lifespan of arcade displays. For CRT monitors, recapping and adjusting the flyback transformer may help, while LCD screens might require panel replacement. Always check power supplies and connections first when troubleshooting display issues.
