Introduction
Since B & W did not respond to my repair request, I decided to open the device myself to repair it.
For me it was just a blown fuse.

Da B&W nicht auf meine Reparaturanfrage reagierte, habe ich mich entschlossen, dass Gerät selber zu öffnen bzw zu reparieren.
Bei mir war es nur eine defekte Sicherung.
