Hello,
I was too lazy to dry my hands, so I used my MacBook Pro 15-inch 2017 with wet hands. And after using it approximately minute - left speaker started arcing inside, and now sound is muffled from left speaker (only subwoofer works, I think). Device warranty expired.
So, can speaker be replaced without replacing whole top case?
MacBook Pro 15", macOS 10.14
