MacBook Air 820-3437 not working after backlight fuse changed
So I bought a 13” Macbook Air with an 820-3437 logic board that the owner said the backlight went out so he took it to a shop to have the backlight fuse replaced. Well I guess the shop replaced the fuse, doing a poor soldering job at that but also rendered the computer unresponsive. i get a solid PPV342 but PPBUS is oscillating between 8.6 and 7 volts. I hear a ticking sound around the SMC area. could that be shot even though I am getting PPV342? I am at a loss on this one.
