Macbook m1 Air screen issue

My macbook m1 has been having an issue with it’s screen, the screen brightness is very low and there are several vertical black lines, I’ve had this issue 2 times before and have managed to get it fixed at an apple repair center, This is the third time I’m having this issue, and it seems that everytime I go to apple it only seems to be a temporary fix. To change the screen apple costs around 470€ and makes me unhappy that I continue to have the issue with their macbook m1 air. I’m afraid that if I were to go to apple repair, they’ll charge me the 470€ and it will yet again be a temporary fix. Any suggestions on what I should do with the macbook?
