I have a Genie, re capped power supply, did ground mods, cleaned all edge connections on boards, and installed a pascal sound board (sound was out) Worked great for about 4 months, now sound cuts out for no apparent reason in the middle of a game. Re booting/resetting game restores sound, only to eventually cut out again. Cleaned edge connectors, still having same issue. Any suggestions on how to clean the molex connectors? I scraped with a razor blade....

Yep, hopefully replacing the pins will work. (not something Im looking forward too BTW) I emailed Pascal, he asked me to send him pics of the board (PI-FX board) which I did. He actually had me replace capacitor C10 he said they had a run of defective ones. I did, but It didn't solve my issue. I debated whether to share this in public but in case someone else has the same problem I recommend contacting him and sending him a pic of C10.

I questioned Pascal on this very thing, I thought irregular voltage (possibly through dirty adjustable pot on A2?) was causing power interruption/A7 failures. Pascal stated that his board does not rely on ANY voltage coming from power supply, it generates its own onboard voltage. I found this very interesting. I did rebuild the power supply (Big Daddy Cap. kit) and did ground Mods when I got the machine. He asked if the green "Heartbeat" LED was still flashing when sound cuts out, which it either locks on solid or off solid. Rebooting the game restarts the A7 to normal operation. nest step is to re-pin connectors, Ima start with A7-J1 and A3-J2 although I have cleaned them all and they fight snuggly.
