I'm having a problem with my 13" MPB TB (16 GB, 512 GB), where when the brightness is set below 75%, the backlight turns off, and then when I increase the brightness above 75% the screen turns on again. Has anyone else had a similar issue, or any idea how to fix it? I've already tried reseting the SMC and NVRAM. Thanks in advance :)

One long long shot but try to reinstall macOS.
Clean install.

If that don't work then leave it for repair.
