Macbook air 820-00165-A no backlight repair

The MacBook switches on but the screen has lost its backlight making the screen impossible to see. This has been caused by some liquid being accidentally spilled onto the keyboard. The liquid seeped down through the MacBook and onto the part of the logic board that controls the screen driver, causing damage.

Remove and clean the logic board of any residue. Diagnose any faulty componants associated with the MacBook backlight driver and replace them. Clean, reasemble and test.
