Hi, Sadly my MacBook Air decided to learn how to swim... and half drowned. As Apple would not take it under warranty (understandably), I followed the fixit teardown step-by-step to dismantle the computer. Carefully cleaned and dried everything and the MacBook Air came back to life. Only that now the screen has vertical bars on it as show in the picture So I'm not sure if this is the Screen failing, or the Motherboard (that has the graphics card inbuilt). Anyone can provide advice ?
