Troubleshooting a CRT based arcade monitor can be a pain. But it doesn’t have to be! The solution is to use the Electrohome G07 flowchart to troubleshoot your monitor!
In order to troubleshoot electronic boards and circuits for arcade games you generally need to have some detailed electronics training. With the G07 flowchart we reduce some of the troubleshooting down to its basics by providing a step by step order of operations for checking the most common components for failure.
How to use the G07 Flowchart
Simply start at the START HERE section of the flowchart and follow each step until you have identified the problem with your G07 monitor.
Once you’ve reached the symptom for your issue the flowchart will recommend a component to replace (or adjust). In some cases you may be able to swap components to see if a problem moves. For example, if your monitor is missing red, you can swap the red and green transistors (i.e. X101 and X103). If the green goes out, but red is restored you can be sure that you have a failed transistor before ordering unnecessary parts.
If your monitor has multiple issues, you may have to return to the START HERE and re-follow the chart to find the next issue and its potential solution.

Warning and Risk of Shock
When using the G07 flowchart, you must be aware that you are troubleshooting electronic components with voltages from 5V all the way up to 60,000 volts. The risk for electric shock is high. Troubleshooting should be performed with the monitor off, unplugged, and the CRT discharged. You assume all risks!
