dropped camera, screen only shows pink lines

Actually, in this case, there's only 2 options here.

1. Check if there are no damage to the cables inside or if they are dislocated.

(You might want to check if no other components are damaged aswell)

2. Buy a new screen if you've confirmed it's the screen, not the cables (In that case just buy new cables).

(Note if you can't do this yourself, I'm sure there's a local repair shop that can do this, you just need to buy the components that need to be replaced (If they don't have them))
