My M2 MAC’s Touch Bar is working, but it is not lighting up,

I’ve restarted, it worked and not working again.

I’ve did system diagnostics, but it showed nothing.

It seems like working but not lighting up, I used `CMD + SHIFT + 6` to take a screenshot of the Touch Bar?

Can apple or anybody else tell me how to solve this without replacing this costly bar?

screen shot comes direct from the GPU.

No SMC or NVRAM on the M1/M2/M3 SoC.

The best you can do if you have an issue— equivalent Shut down, close the lid 30 secs+ , reboot as normal.

If no resolve try SafeBoot Use safe mode on your Mac - Apple Support to sort anomalies.
