if the backlight on my macbook air is not working due to water damage

[Taylor_8]

do i have to replace the LCD or the Backlight? or is it not repairable. Could the backlight be part of the motherboard what is the best approach when fixing the backlight by itself? please help. again this is Water Damaged. Is it worth spending 200+?? or more to fix. thank you.

So if you shine a flash light up the dark screen and you can see the image, then the LED (assuming a modern LED display) or the circuitry driving the LED needs to be fixed. If no image, something more serious.
