Troubleshooting Arcade Machines: Common Faults and What to Look For
Posted by Austin Amusements on
Welcome to Austin Amusements trouble shooting blog, where we dive deep into the world of arcade machines and tackle the common fault-finding issues that can leave you scratching your head. In this post, we'll explore a few specific scenarios: when your screen doesn't turn on but you hear game sound, when your machine seems completely unresponsive, and when the screen is on but the game won’t start despite the power supply light being lit. Let’s get into it!
Scenario 1: Screen Doesn't Turn On, but Sound is Present
This issue often suggests that the machine is partially operational. Here are some quick steps you can take to troubleshoot:
1. **Check the Connections**: Make sure that all video cables, such as the VGA or RCA connectors, are securely attached. Sometimes, a loose connection can disrupt the display signal.
2. **Inspect the Monitor**: Look for any visible damage or burning on the monitor. If you're using a CRT, check the neck board for any burnt fuses or components that may stand out.
3. **Component Failures**: If you have access to a multimeter, check the monitor's power supply to ensure it's receiving the correct voltage.
4. **Game Board Issues**: It’s also possible that the issue lies with the game board itself. If you have a multi-game board, try swapping it out with another one to see if the problem persists.
5. **Capacitor Condition**: Sometimes, failing capacitors on the monitor can cause the screen to go black while the audio plays. A visual inspection for bulging or leaking capacitors can save you some headaches later on.
If your Chassis is faulty and you can remove it yourself we recommend sending to JOMAC in WA for repair.
Scenario 2: Machine Turns On, but Nothing Happens
If the machine turns on and there’s silence, but everything else seems dead, here’s what you should check:
1. **Power Supply**: Start by examining the power supply. If there’s no light indicating power, it may need to be tested or replaced. A good power supply is essential for the entire system.
2. **Fuses**: Check for blown fuses either on the power supply board or on the main board. This can often be a simple fix that gets you back in the game.
3. **Switches and Buttons**: Ensure that the start buttons and coin mechanisms are functioning correctly. Sometimes, a stuck button can prevent the game from starting.
4. **Main Board Connections**: Disconnect and reconnect the cables on the main board to ensure there isn’t a loose connection causing the problem.
5. **Grounding Issues**: Verify that the machine is properly grounded. Ground issues can lead to an array of failures and performance inconsistencies.
Scenario 3: Screen is On but Blank, Power Supply Light is Lit, but Game Does Not Start
In this scenario, you have partial signs of life, but the game just won’t kick off. Here are some areas to focus on:
1. **ROM Chips**: Corruption or failure of ROM chips can prevent games from loading. Check for any signs of damage, very carefully pop the chips out slightly and push them back into position, then turn on the machine to test. If nothing changes you may need to replace the chips to see if it resolves the issue. Best to send your game board to us or another repairer.
2. **CPU Board**: Inspect the CPU for any obvious signs of damage or overheating. This component plays a crucial role in the overall functionality of the arcade machine. If you have a multi arcade game board, several models are know for overheating and in most cases need to be replaced.
3. **Diagnostics Mode**: If your machine has a diagnostic mode, engage it to check for error codes or other indications of what might be wrong.
4. **Wiring and Connectors**: Inspect all connectors and wiring harnesses for any signs of corrosion, breaks, or loose connections. Sometimes, an overlooked connection can be the root of the issue.
5. **Test Different Games**: If you have more than one game board, try swapping them out to rule out any issues with the specific game.
