My futher discovery is:  
The broblem looks like to be in the backlight module. Each time I import the module I get the message.  
So where do I have to correct?  
Or is there a new backlight module?

This error lookslike that at: [Display-O-Tron HAT i2c problem](http://forums.pimoroni.com/t/display-o-tron-hat-i2c-problem/981/3)  
I have tried to reactivate i2c and reboot and run the backlight.py-program and still get the error.
