Ergodox one row dead after water spill

[hundenapf]

After a year or so of happily using my Ergodox I have finally spilled some water into it. Now the second row on the right side is not working at all anymore. I have thoroughly dried it, cleaned it with alcohol, resoldered some connections, still no sign of life from this single row. What could be the cause of this and what should I do next?

Check Ripster Guide: ACK! I spilled something, WHAT DO I DO ... maybe you'll find something you can try:
