Monitor flickering in arcade machines can ruin the gaming experience, but understanding the causes and solutions can help. Here are the most common reasons and their fixes:

1. Loose or Damaged Cables – Flickering often results from loose or frayed video cables. Check connections and replace damaged cables to ensure a stable signal.

2. Failing Power Supply – Insufficient or unstable power can cause screen flickering. Test the power supply and replace it if necessary.

3. Degraded Capacitors – Older CRT monitors may have worn-out capacitors. Replacing them can resolve flickering issues.

4. Interference from Nearby Electronics – Other machines or devices can cause electromagnetic interference. Reposition the arcade machine or shield the monitor.

5. Incorrect Refresh Rate or Resolution – Mismatched settings can lead to flickering. Adjust the monitor’s refresh rate to match the game board’s output.

By addressing these issues, you can restore your arcade machine’s display to its optimal performance. Regular maintenance can also prevent future problems.
