I had a perfectly working machine. I decided to clean up the boards with some IPA to make them all pretty. While doing that, I noticed a few corroded pins on the ribbon cable connector 'S' (main PCB side). Pulled out the soldering iron and retinned a couple pins. Did not go as planned because when I put everything back together, I now have no sound output (everything else works). I tried to find the pins I soldered but can not find them in the schematics. They are S-9 (pin #9) , S-I (pin #9 second row) , S-J (pin #10 second row). I am kind of confused on the pinouts for the ribbon cable because in the schematics there is an S-P which means it skips at least one letter since P is the 16th letter in alphabet and there are only 15 pins. Can someone lead me in the correct direction on what I need to look at? Also, if anyone is in the Phoenix area and would be willing to let me try my sound board in their machine, that would be awesome.
Thanks,
Shawn
