Hi. I have 2015 MBA 11" with no backlight due to water damage. Other than the backlight, it appears fully functional (including LCD). After cleaning and inspecting the logic board (820-00164-A), I found broken backlight fuse (no continuity), apparently no short to ground on both sides of the fuse and screw holes (no beep), and LVDS connector with heavy burn on the backlight side (side towards the backlight fuse). So, I am planning to replace these components. Is there anything else that I should worry about? Thanks for your help!!
Nope. Just replace the LCD connector if burnt, will need to replace the LCD cable too (usually the plastic melts around the gold pins, or the gold circles on the bottom of the LCD cable are dull, which can blow the connector). I have not seen a MacBook with burnt LCD connector, where I have been able to confidently plug the old cable in, this usually gets wrecked. When replacing the cable, be careful when removing the silver screen bezel at the bottom, to make sure you don’t cut the screen ribbons.
