Hi, I am asking for a little troubleshooting advice.
The laptop seems to boot up fine. Caps lock is working, the touch pad has haptic feedback, and even the "charger plugged"-sound is present.
Power consumption is about 15-30W at boot and idles at about 20W.
Unfortunately, the display and the touch bar are completely black (No signal and no backlight).
I don't get a signal on an external USB-C display either. Also not in safe mode.
