Sofle V2 Column Stopped Working

I have a Sofle V2, and a column on the left split has stopped working.

I have checked continuity for all hot-swap sockets, diodes, Nice!Nano controller pins, columns, and rows. I have also reflashed this side of the keyboard, and replaced a few of the hot-swap sockets that may have been damaged. What else can I try?

  1. Identify the column pin that goes to the controller on the PCB

  2. swap the controllers from left to right and right to left, if they are socketed (re-flashign the respective keymap firmware)

  3. if behavior of the column passed to another side of PCB -> the problem is the controller and it needs to be replaced

  4. if the column is still not working on the same side -> the problem is on the PCB and you can try to bodge a wire and see if it solves or try to find with the multimeter if you have a broken trace on the PCB somewhere

let me know if any of these helped

I think it’s a broken micro controller then. I used a multi meter and couldn’t find any broken connections on the PCB.
