Hey Pinside!

I'm pretty novice when it comes to electrical and switch Matrixes. I've recently run into an issue after changing out the flipper assembly on my Sorcerer machine.
It seems activating one switch is triggering the entire row of switches. Going off the Matrix on in the manual, when any switch in row 4 is activated, all of the other switches register as well. So hitting the center coin will trigger the C in Sorcerer, D on the roll overs, Outhole, Right Drop Target, and Lane Change.

I've followed the entire loop and don't see anything out of place. There was a point were hitting the C switch would do nothing, and you could only light up that letter by hitting a different switch from the row.

Any thoughts or advise?
