My recently acquired MSI GV72 only has a black screen. The keyboard lights you hear ventilation, etc. And the on / off button flashes when you turn it off. In a state when it is on, it shines all the time. The screen always stays black.
You probably came on one of the Fn buttons, and turned off the screen?
Or something like that? https://forum-en.msi.com/index.php?topic=256394.0
Does not work… Have installed only programs like Steam, Teamspeak, Discord and games!
Works again, suddenly started again.
