Korg B1 - specific notes don't work, problem with circuitry
Aloha all, I just purchased a Korg B1 digital piano with known issues. The keyboard sounds great but has specific notes that don’t work. Starting from the E after middle C, all Es, Cs and G#s don’t work.
Luckily, I found another ifixit post, the only place on the internet it seems, where someone understood why specific notes wouldn’t be working. Here is the link: ++"E" key and 3rd black key is not working.
I understand very little about circuit boards, but I was able to identify the problem immediately. C, E and G# receive and give inputs along the same path. There is an issue with the soldering on one of the *things* at the first E key, where the problem starts. See the images for this issue.
So, one of my problems is that I don’t know anything about circuits or circuitry terminology, so I can’t even describe this issue, much less start to fix it.
Can anyone help me at least put a name to this, so I can start to go about fixing it? It seems like a basic circuitry issue that wouldn’t be hard to fix, but I don’t know where to start. Any help is appreciated.
