If the earphone is unhealthy, please confirm it because there is a case to be solved by the part exchange of this part.
First of all, the work of removing the inside cover by turning the inside out of the main body is done first.
Because there is a screw in the place which is enclosed in a red circle, it removes all, but it is not possible to open it with a Phillips screwdriver because it becomes a screw of a special shape.
Pentabebe driver (star type), can be opened by using the Torx screwdriver, but we have used the driver of BEST 8800C 1.2.
If all screws can be removed, it will be possible to remove the back cover, but care must be taken.
When disassembling MacbookAir and MacbookPro, we will remove the back cover in the same way, but it is necessary to open it from the opposite direction from those models, but here we will only work to lift lightly using a spatula.
If it floats overall, I will open it, but please be sure to lift it from the same position as the image.
If you open from the opposite side, there is a possibility of disconnection because there is a cable, so be careful.
When the back cover is lifted in the previous process, it becomes the first visible part (trackpad), but we will work to remove the connector that is enclosed in a red frame.
I was able to open the back cover somehow with this, but it has not been completed yet.
Now it knocks it backwards from the image.
If you want to explain clearly, wake up the lower side (trackpad side) in the image so that the opposite side (battery side) is put to sleep.
If it is difficult to do, please put the thing which becomes the back rest in the back so that it does not fall down.
This part is connected to the battery and the logic board, but remove the screw attached to the red circle part.
When the screw can be removed, the iron plate under it can also be removed.
The pick and the spatula (plastic) are sandwiched into the gap where the screw was removed, and the electricity is cut off.
Then, let's remove two screws of the red circle part which is in the immediate vicinity.
This part is called Audio Jack Board, but it becomes the earphone part.
Since a fluent cable is connected from the logic board, you can pull out the cable if you lift the black nail of the arrow part and slide it.
This part becomes a cable connected to the logic board from the liquid crystal panel, but because a black seal is affixed to the connector, I peel it off first.
Since the structure of the connector has changed a little, please disassemble after understanding the structure without forcibly proceeding with the decomposition.
You can easily remove the cable by causing the previous nail and sliding the cable.
Next, the screw which is enclosed in a red circle is removed as much as 2 really.
That's all there is to it.
It is also possible to omit the process up to this point, but if you are not confident in disassembly because it is easy to understand, please proceed with the same procedure!
