Hey Noek, thank you for you reply and your suggestion. 
The solution from the other topic you suggested, sadly doesn’t work for me, I didn’t change any backlight options. 
I couldn’t see anything during startup, that would relate to my problem. 
Regarding debugging, I am far from an expert. The thing that i tried was to check the i2c connection to the display with i2c tools, which showed me a connection on port 27. 

I don’t know wether I am missing something, but I would rule out a hardware problem (meaning physical connection or fault of the display or raspberry pi hardware)  because it works, with the exact setup, just a different software. I would guess it has to be a configuration issue of some sort 

Maybe someone has a clue what’s going on, or some concrete trouble shooting steps? 
I would greatly appreciate your help
