I had no idea if I could fix it, I just wanted to find out what exactly was wrong.
Now that we have the screen out, the chrome with white border is a casing on the backlight, so I took it apart by peeling it off gently, by the white plastic frame.
Here we are, the chrome part is out, the backlight is naked and you see that transparent plastic part lying there. This is like a fibre optic transmitting light from the LEDs to the whole screen. This was damaged by the Acetone.
