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! :)

Or will I need to consult someone else IRL? I would very much appreciate if someone could tell me how I can get around this issue.
