I just put an MK4 pcb in my cabinet which has a 6 in 1 switcher. I noticed that the screen gets wavy at the settings menu of mk4. Almost looks like the screen rolls around the edges. It barely does it but it is noticeable. Makes it look like you are tripping. I also noticed it doing it on MK1 game play. Sometimes when playing mk4 in the level with the rain, some of the sound effects get missed or cut short. Not sure if this is normal or something else is causing this. I wanted to test the voltage at the peter chou and when I touched the probes to the power supply 12 volts positive and to the ground, the game shut off. For a minute or two, only the marquee would come on. I unplugged it and removed the two fuses from the isolation transformer. Eventually it started working again. Not sure exactly what happened. I had the test meter on dc 200. The game was on. I wanted to test the voltage because I have 4 fans hooked up to the power supply and I wonder if they were draining voltage. I believe that all my issues are because of a low voltage issue. Any ideas how to turn the voltage up on the peter chou? Do I turn the know towards the H?
