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! :)
Esta é uma boa pergunta?

Hi, how did you manage to open the piano?
I really cannot find the way to disassemble it. I removed all the screws from the back and still don’t know how to access the part you showed here.
Can you give some indication please??

I'm having this exact issue. Any chance you were able to get it figured out. All I can guess is the circuit board is faulty but I have no experience working with things like this. My bad keys would be in the third octave from the left and they are the F, F#, G, G#. I have moved the rubber contacts and have confirmed they are not the issue as those contacts work on other notes and other contacts that work on other notes do not work on these notes.
