I'm in the process of rebuilding a Williams Firepower and I've been slowly rebuilding the Driver board as a few IC's were bad on the solenoid section. After rebuilding that side, it has played great for about a month! Now I'm having an issue where several switches stop working all at once. I have traced it to the 2J3 switch row and specifically the White/Brown wire 2J3-9. There is no short anywhere in the wire and when I reseat the connector it will comeback. Sometimes if I let it just it it will also come back. Does this sound like a IC issue on the switch section of driver board? If so, I can't find the correct IC part#MN14049 Invert, Hex Buffer. The closest I can find is MC14049. I sure hope I've explained this good enough lol!!

I have not. I will try that first this week and see if that helps. Thank you.

Reflowing the solder on the connector has worked for now. Still going to rebuild the switch section on the board. But at least she's back working!! Thanks!!
