Bought my upright a week ago. Was working just fine. Then all the sudden in between me swapping PCB's from one game to another. The sound just stopped! I know the speakers work, as I tried my iPod with them. But for some reason I'm not getting anymore sound. No matter what PCB I try. Any advice would be clutch. Thanks!

Hey guys! Just joined up and bought my very 1st machine! NBA JAM! Been doing some research over the past week, but now i think I got the basics of everything! Nice to meet you all!
