I broke a MacBook Air backlight by connecting a faulty screen
I received 2 13” Macbook Airs in need of repair: a 2014 model with a cracked (but semi-working) screen, and a 2015 model with water damage, which caused its backlight to fail (but it did work using a flashlight).
When I disconnected the LCD cable from the water damaged Macbook, a few pins on the right side looked slightly damaged, presumably corroded. Wanting to make sure that the backlight issue was caused by a logic board issue, I then swapped the logic boards and connected the water damaged logic board to the cracked LCD. Same thing: no backlight.
Here’s where I made a mistake: to check if the screen on the water damaged Macbook Air was salvageable, I then connected its damaged connector to the good logic board from the other Macbook. I got no image when booting, and then noticed a faint burning smell. I disconnected the battery, and realising I might have made a very bad mistake, I swapped the boards again to see if there was any damage.
Now, the “good” logic board connected to the “good” (but cracked) screen no longer shows a backlight. With a flashlight, I can see the cracked (semi-working) screen. So I basically broke something on the 2015 logic board by connecting a bad LCD connector, causing the backlight to break. Is there anything I can check / do?
