Hello guys my macbook pro 2015 13 inch have a weird problem

Hi guys i have a problem with my mbp 2015 13inch , it works perfectly but the problem is when i trynna get to boot menu its starts but on black screen i can choose only by guessing, also with fileVault when i activate it and reboot my pc when it gets to the place to write the password i write it by guessing on a black screen and press enter and wait if its right.

btw it does it also at the startup of the pc when i hear the bamm sound it stays for 3 secondes or 4 on black and then i see the apple logo but the loading bar is already on the middle like the step of the first startup cannot show on screen .

i tried reinstalling macos, doing the smc and nvrams and every shortcut that helps the pc to get over it and nothing works , i tried opening it and disconnect the ssd and batterie and reconnect it again but nothing works and idk , i can not do a bootcamp or something like that om afraid i get to the boot menu and get stuck there with a black screen without knowing where to go.
