Okay so pcb works perfect except it's missing soundFX. Music & video works great.
It's definitely not the audio amp or any wiring in the cab since I have another Outrun pcb that works perfect in the cab.
All the socketed chips have been tested on another working pcb and they're all good. The pcb also passes the Rom & Ram self test all good.
I narrowed the problem down to the top board since the bottom board works with another known good top board. It should be noted I fixed graphic glitches on this board when I found 3 spots on the back of the bottom board that had bent pins touching other pins. when I separated them the graphic glitches were gone. I know to look for other bent pins, and broken traces but anything else I should look for in this type of situation?
