Hello,
Touch Bar only show Brightness, Volume and Mute Volume, with the expand icon. If I tap the 'expand' icon on the Touch Bar, it expands to show all the icons but then the entire Touch Bar goes blank....
I rest the SMC and NVRAM/PRAM nothing changed
Please advice
To trouble shoot further you can:
—Try a SafeBoot https://support.apple.com/en-us/HT201262
—Test issue in another user (or guest user) account https://support.apple.com/en-us/HT204443
The two software fixes—If this is a Intel Mac , you can hold for" 3-4 sequences of resetting" in an effort to elicit a change, no harm here.
Try resetting the SMC https://support.apple.com/en-us/HT201295
Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

If no resolve I suspect you have a hardware problem. The Touchbar is control by the T2 chip
In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment
