I picked up a BK as a project pin a few weeks back. When I walk through the switch test it tells me that 39, 31, 23, 15, and 7 switches are closed. I looked it up and that is row 7 of the switch matrix. A quick Google search brought me to the PinWiki for Williams. Following those instructions I pulled J2 and J3 from the driver board. Even with the connectors out, every switch on row 7 is showing closed. I have a logic probe on it's way to me now, but I am thinking that 1 or both of the switch row IC's are fried. They have F4049BPC stamped on them. Can someone point me to a place where I can order replacements?
This should prove interesting as I am at the very early learning curve with my soldering skills.
