Touch Bar working but the display doesnt

Ive had my M1 2020 MacBook Pro for about 3/4 years and within this I've had my Mac sent to apple and sent to another country for it to be fixed twice already. and can't be bothered with not having my Mac as I need It for uni and all they seem to do is restart it to factory settings. my Touch Bar was working fine until earlier this year when the display no longer turns on but it still works. I have done everything to try and fix it- restarting, activity monitor, terminal, settings and nothing works.
