I experienced the problem described in my thread, here, just now. Since then, the screen of my MBP 2016 has remained black (not lit up at all) and I am unable to interact with it - pressing any keyboard buttons will not awaken the display, the trackpad is still active however. Occasionally pressing the keyboard buttons will illuminate the Touch Bar, to which I am then able to use Touch ID to unlock the MBP. However the screen remains inactive - though this has nothing to do with the setting of the display brightness. Long-pressing the Touch ID/power button in an attempt to 'force shutdown' does not do anything.
