2019 MBP 16" - Regardless of the version of MacOS I have had installed on this device, on several occasions the screen fails to wake after it has been sleeping. This usually happens when I disconnect it from my LG UltraFine 24" display which is connected via USB-C (power and video/audio). What happens is I open the display lid, the Touch ID controls will light up and are functioning (I can hear the volume level changing, etc). Not sure what you call it, but I think the "backlight" or something else is wrong. You can see the faint blue/blackish tint of the screen, just no icons or interface. A force shutdown and the startup always resolves it, but I don't like doing that for fear of software corruption. Is this a full logic board replacement or something?
