Touch Bar works, but don't lights up - sometimes flashing only

Hello all!

Suddenly (I haven't noticed when exactly) Touch Bar became dark (MacBook Pro 13 m1), but working: changing volume, mutes, etc.

Some times flashing/lighting up when opening laptop and in middle of operation. Can be done smth without physical repair/replacement?

P.S. All things like restarting Touch Bar process / cash cleaning / changing Touch Bar settings (listed her https://iboysoft.com/howto/mac-touch-bar...) are done. Haven't reinstalled OS yet.

This sounds like it's most likely due to a hardware issue, possibly with the TouchBar connections to the main logic board. I think the next steps would involve opening up the device and inspecting those connections and the surrounding logic for signs of damage. Best of luck!
