Response from Jonathan: Some Dynamo cabinet models allow you to access the components from the front. You might try unlatching the control panel as it may be located on a drawer that you can pull out that has the PCB, power supply and isolation transformer on it. Some of these cabinets even have a hinge that allows the monitor to tilt forward so you can work on it. Of course, all of this depends on the type of cabinet you have. Check out our post on Opening An Arcade Cabinet for more information on how to unlatch the control panel.

Hope that helps. Thank you for your question and good luck with your repair.
