I recently got an arcade machine in pretty rough shape that I am planning to turn into a 60-in-1. The game that was in it was partially functional when I powered it up, in that it would boot to the main screen but there was some flicker (just assumed it was due to ancient monitor).
Anyways, the attached picture shows the power supply that was used for the game/monitor. My brother helped me pull everything out of the cabinet and obviously couldn't keep his hands from messing with the red dial at the top of the power supply. When I went to test it out by using a 110V mains connection to the AC connections and the GND to FG, it made a weird pulsating humming noise and the voltages were not clsoe to expected. ~2V on the +5V rail and something like 6V on the 12V.
It didn't make sense to me that the game would boot up with the voltages this far off, so the only thing that comes to mind is the adjusting of the dial. I tried twisting this and powering on and off a few times but had no luck.
Any ideas how to get this working?
