You sure liquids didn’t just get inside the backlight layer? If that has happen then it’s game over either replace the screen or the backlight behind the screen (requires soldering). Personally I would not even bother replacing the backlight and just replace the screen since it’s been affected by liquid damage and easy to get dust in when trying to change backlight.
