Screen flickering in arcade displays can ruin the gaming experience and even damage equipment over time. To prevent this issue, follow these proven methods:

1. Check Power Supply Stability: Ensure your arcade cabinet has a stable power source. Voltage fluctuations often cause flickering. Use a surge protector or voltage regulator.

2. Adjust Refresh Rates: Mismatched refresh rates between the game board and monitor can lead to flickering. Configure both to compatible settings (e.g., 60Hz for most CRT displays).

3. Inspect and Replace Cables: Faulty or loose video cables (VGA, RGB, or DVI) are common culprits. Replace damaged cables and ensure secure connections.

4. Capacitor Replacement: Aging capacitors in CRT monitors degrade over time, causing flickering. Replacing them (recapping) can restore display stability.

5. Avoid Magnetic Interference: Keep speakers, power supplies, or other electronics away from the monitor to prevent electromagnetic interference.

6. Update Firmware/Software: For modern LCD-based arcades, ensure the latest firmware or driver updates are installed to fix compatibility issues.

7. Monitor Degaussing: CRT monitors may need periodic degaussing to eliminate magnetic buildup that causes flickering or color distortion.

By implementing these solutions, you can maintain a flicker-free arcade display for seamless gameplay and longevity. Regular maintenance and proper setup are key to preventing recurring issues.
