Thank you sir, I have a1466 macbook and little water damage and immediatley shut down the pc and wait closed 3 days. Then opened and saw D7701, L7701 occidated and XW7720 button burned. Other every thing is fine (capasitors C7796,C7797,C7799 and U7701 IC etc. no damage or occidation). There is no backlight like your video. I am concern about to fix burned and rusty XW7720. You did new wire line but i dont understan where it starts and where it stop (you scratched somewhere and made a wire line). May i ask how works D7701------XW7720------L7701 connection?
