SF2 Championship Edition arcade recently purchased. When I first turn it on no sound. let it run 20-30 seconds turn it off then back on and sound works flawlessly. I can then turn it on and off 20 times in the hour and it works perfectly every time. I'm leaning towards the power supply needing adjustingment but I want all ideas before I start messing with it. The previous owner did a cap kit on the pcb. Can a pcb capacitor warm up in 20 seconds? Seems not long enough for the solder to warm if it was a solder contact issue. Appreciate any advice. Game and sound works perfectly after I turn it on and off.
