Hi, I bought a Pre-Built Zynthian V1 and none of the 4 rotatory buttons are working. When I received it I plugged a 16GB SD card with the OS on it, and everything worked, the touchscreen works too but none of the buttons work. I’m using a 2,4A Micro USB adaptater so I don’t think the problem comes from the power. I’ve also openned it to check every connection but everything seems plugged correctly.
Thank you in anticipation of your answers.
