All the keys from G to C on the right side of the board do not work
I have marked the keys that do not work in red on the image below.
I have taken apart the keyboard and came to the conclusion that the issue could possibly be the resistors on the board under the keys. I was unable to locate any schematics or information about the board and I am unable to identify what resistors they are.
The image is not super clear, I will have to get a better one when I get a chance to do so.
