Arcade machines are built tough, but like any electronics, they can develop issues over time—especially vintage models. Whether you own a full-size cabinet or a mini arcade machine, knowing the most common faults can save you time and money.
🔧 Most Common Arcade Machine Fault: Display / Monitor Problems
Why?
-
Old arcade machines mostly use CRT (cathode-ray tube) monitors, which degrade over time.
-
Issues like flickering screens, no picture, color problems, or distorted images are frequent.
-
High voltage components inside CRTs can wear out or fail.
Signs to Watch For:
-
Screen flickers or goes black randomly
-
Colors look faded, too bright, or off
-
Image is stretched, squashed, or skewed
-
No picture but sound and controls work fine
How to Fix:
-
Check connections: Loose or corroded video cables can cause display issues.
-
Adjust monitor settings: Brightness, contrast, and geometry controls may need tweaking.
-
Replace capacitors or tubes: If you’re comfortable with electronics, replacing aging parts can revive the monitor.
-
Professional repair: CRT repair specialists can fix or refurbish vintage arcade monitors.
-
Consider upgrading: Some owners retrofit arcade cabinets with LCD or LED screens for reliability.
Other Common Arcade Machine Faults
1. Joystick or Button Failures
-
Wear and tear on physical controls is very common.

Buttons might get stuck, or joysticks become loose or unresponsive.

Solution: Clean, lubricate, or replace worn parts. Many replacement kits are available.
2. Power Supply Problems
-
Old power supplies can fail or cause inconsistent power delivery.
-
Symptoms: Machine won’t turn on, resets randomly, or behaves erratically.
-
Fix: Check fuses, test power supply voltages, and replace if needed.
3. Game Board / PCB Issues
-
Circuit boards inside the cabinet can develop solder joint cracks, corrosion, or component failures.
-
May cause crashes, freezing, or no game startup.
-
Cleaning contacts or reflowing solder joints can help.
4. Coin Mechanism Problems
-
Jamming or failure to register coins/tokens is common in commercial arcades.
-
Clean or replace coin slots and sensors.
