4 piano keys not working (seems electronic problem)

Since a few days ago, four piano keys on my 2'5-year-old Korg B2 piano have been not working at all.
I disassembled the piano, cleaned it, and tried to replace the rubber/carbon pads of the problematic keys with other ones from another octave, but nothing changed. It seems somehow to be a problem in the circuits.
The non-working four keys are located adjacent to each other and look like they are in the same group:

I would like to highlight that I'm completely ignorant in this area of knowledge. I did check other posts with similar problems, but I don't know where to start checking in this labyrinth of circuits.
Any ideas, guys? I would much appreciate some expert eye in here and proper guidance on what to do next.
Thanks in advance! :)
