My Macbook isn’t turning on

Hello, today i just opened my laptop and the screen isn’t broken nothing is wrong with the screen, no scratches cracks nothing but it just doesn’t show anything on the screen, the keyboard lights up when it’s turned on but nothing displays on the screen, i tried to press shift and it makes noises but for some reason it isn’t turning on and nothing is wrong with it like i just got the screen repaired not that long ago but now it’s just not turning on and it charges properly it just doesn’t turn on for some reason
