Hi,
I bought a rpi 5 and got the idea that I could revive my old project. So I combined three things that I have:
- ZynScreen 3.5 (v1)
- Raspberry pi 5
- Behringer 404 HD
In webconf, I got everything working as expected.

The only problem is, ZynScreen is white and nothing is visible on it. When accessing via VNC everything works. I can load selected snapshots, play midi, all without problems. Only white on the LCD panel…
I turned on UI log and this is what I found:

Well, my observation matches the UI log, the brightness is the problem.
Please can someone advise me what to do with this?
