Today as usually at work Im trying to open my MacBook Pro, there's no opening tone also the touch bar lights is off. But the power button and finger print are still work.
I try Google to resolve the problem, nothing was ever clear.
Please let me know if it software or hardware problem, and how to fix it.
Accept my regards
MacBook Pro 13", macOS 10.14

If your TB Mac is from 2018 you need to follow instructions for the T2 security chip on those pages.
in any case if you are using a touch bar app or plug in you should remove it from the equation.
