MacBook Air 13″ A1466 820-3437 No Backlight Liquid Damage Repair
MacBook Air 13″ 2014.
The backlight was not working due to liquid damage. After inspecting the logic board and the schematic we found out that the backlight fuse was damaged, therefor we changed it. The backlight was back to working. We then cleaned the logic board in the ultrasonic cleaner, we dried it and assembled back the laptop. Job is done !
