How to Troubleshoot Video Arcade Games

Use a multimeter to identify problems with your arcade machine.

A coin-operated video arcade can dress up a recreational room, or even provide supplementary income. Moving these large machines is difficult, but once in place they typically require little maintenance. When problems do arise, they can be quite complicated and expensive to repair. Learn to perform as many troubleshooting and repair steps as possible to avoid service calls and save money.

Things You'll Need

• Multimeter

Instructions

1. Verify that the unit is plugged in a working power outlet. Turn off the machine's power and let it sit for 30 second before restarting it.

2. Check for noticeable signs of external damage, including burn marks, water damage or cut wires. The machine won't function if power cables are cut or its controls damaged. Make any necessary repairs or replace damaged components.

3. Check the motherboard and any other circuit boards for signs of cracked solder, burn marks, loose cables and connectors within the machine. These will typically be present if the machine won't turn on at all. Replace or reattach any damaged or missing components.

4. Check all fuse banks for blown fuses. If fuses continue to blow, there is most likely a short circuit on one of the boards. Use a multimeter to locate the short. Also use the multimeter to test all cables connecting components to the motherboard.

Tips & Warnings

• If all else fails, a multimeter can be used to detect broken leads, missing components and blown capacitors. If you do not have the electrical know-how to address issues found on specific components of any of the boards, the unit will need to be sent in for servicing.

• When examining an arcade game machine, ensure that the power is off before examining the motherboard or other components. Stay away from capacitors unless you have discharged them. Also, unless you are a qualified technician, don't mess with the monitor's internals in any way, as this can cause a lethal shock even when unplugged.
