I have a macbook air which recently began showing the "lines of death" up and down my screen, a common sign of damage to the LCD panel. I can still login and to an extent use the machine, with the exception of doing so blindly. The model number is A1446, and it is a 13 in. screen. How do I go about making this repair myself at home? Or would it be more worth my time (and nicer to my wallet) to get it fixed at a store or other repair center?
NOTE: I essentially need the repair completed within 24 hours as this machine is a critical part of my work
Also, I dont know the cause of the damage exactly, i went to bed with everything A-OK, and in the morning the LCD wasnt working properly.
