Hey, the visualizer worked absolutely fine at first, but now the screen doesn´t start, it is always white. It seems that only the screen has a problem because the leds react to the keyboard as they should. i have reinstalled the image several times now, but the screen is still not working. Unfortunately there is no error to see anywhere in the terminal. any idea? :(

Hey, I had this problem a few times, it fixed by itself after few hours. You can also try to reattach the screen, maybe the pins are not connected correctly.

the old screen was indeed the problem. The new one works just as it should :)
