My touchbar stopped working... any troubleshooting advice?

Even though SMC controls the touchbar, some USB is in play, so this would be NVRAM (or reboot.) notice:

USB Device: Apple T2 Bus

USB Device: Touch Bar Backlight

USB Device: Touch Bar Display

USB Device: Apple T2 Controller

Try resetting NVRAM/PRAM hhttp://support.apple.com/kb/ht1379 as well.

If both these fail to resolve your issue, you have a hardware problem which will require service.

In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment
