Suddenly the TouchBar has gone blank...
Status:
Installed latest update
Ran Terminal: sudo pkill TouchBarServer (successful)
sudo killall ControlStrip (No matching processes were found)
Several restarts also didn't help

Any suggestions?

Hi,
Try to start up in Safe mode, then normal boot could solve your issue.
Start up your Mac in safe mode – Apple Support (UK)
If it doesn't help, try to check your MacBook Pro with Apple Diagnostics if it reports Touch Bar related error.
Use Apple Diagnostics to test your Mac - Apple Support
If error is reported or doesn't help, you'd better contact Apple support or take your MacBook Pro to your local retail AppleStore, Genius Bar or Apple Authorized Service Provider to be examined your MacBook Pro there.

Thanks for input, @leroydouglas.
Tried all that, no change. Model is with 2,6 GHz 6-Core Intel Core i7 processor, memory 16 GB 2667 MHz DDR4.
Oddly, in Activity Monitor I cannot find Control Strip and in Keyboard Settings TouchBar does not appear. Maybe because Control Strip is not running/absent?
Cheers, kaz-k.
Unfortunately didn't take me any further. Ran diagnostics, but no errors detected.
Took it to a local authorized dealer (Gravis franchise, not apple store), which of course did not have a technician on site. Estimate from guy in store EUR 7-800 for repair...! Ehhh, **** no!
Just sooo annoying.
Seems odd that the Control Strip does not appear in the Activity Monitor at all.
The daemon that control the touchbar may be named Dynamic Function Row daemon, or dfrd.
These problems essentially always turn out to be hardware issues.
