Hi,
I have macbook 2017 and while working, my brightness keeps becoming zero. It is as if somebody presses the F1 (for reducing brightness to zero). I have to press F2 to increase it , only to see it go back to being blank. This is happening pretty frequently and I have tried SMC reset, changing display setting to automatically set brightness level to manual and automatic. These haven't worked.
MacBook Air 13″, macOS 10.12
Open Keyboard Viewer, see if F1 highlights itself when this happens.
