SF2 Champion edition. When the board is cold, i.e. first time turning it on for the day it has no sound. After it has been on for a minute I can turn it off then on and get sound. If it stays warm sound works flawlessly. If I put board in the refridgerator for 10 minutes, same problem no sound. The power supply is working perfectly and the A board has been recapped. I don't think its the z80 because the sound works perfectly when the board is a little warmed up (1 min on). Could it be the 12mhz crystal? I am running out of ideas. What is making it stop working when cold and barely warmed up its flawless?
