iPhone7 power button, volume switch replacement, disassembly procedure, repair method
[iPhone7 power button volume switch replacement, decomposition method STEP 1]
This decomposition method is a decomposition method that is effective when the power button of the iPhone7 does not respond, the volume switch does not work, and is difficult to work.
It has become very long as a decomposition process, it is high as a difficulty of decomposition, it is necessary to remove important parts such as liquid crystal, logic board, please disassemble with due care.
[iPhone7 power button volume switch replacement, decomposition method STEP 2]
I will continue to disassemble the iPhone7 from here, but let's remove each tray of sim card first!
The sim tray can be easily removed using the pins that were included in the accessories at the time of iPhone purchase.
[iPhone7 power button volume switch replacement, decomposition method STEP 3]
Decomposition of the iPhone7 will start from the place where all the screws are removed, but it will be removed from the Torx screwdriver.
[iPhone7 power button volume switch replacement, decomposition method STEP 4]
Since the iPhone7 is waterproof, a waterproof seal is affixed around the inside of the liquid crystal.
The tool in the image is called a heat gun, and it is not necessarily an indispensable tool though it is a tool which made the dryer strong if it says plainly.
If you are new to disassembly of the iPhone itself, you can work smoothly because the seal will be soft if you use it, but it is possible to substitute even a dryer once.
[iPhone7 power button volume switch replacement, decomposition method STEP 5]
Up to now, the iPhone has been to wake the LCD from the home button side to the camera side, but this iPhone7 will open the LCD so as to wake up from left to right.
First of all, the tool is inserted into the position where the spatula is located and it floats little by little, but it becomes easy to disassemble when the suction cup (orange) is used together.
If you try to cause it forcibly, the liquid crystal side will crack, or it will lead to other failures, so we will open it slowly.
[iPhone7 power button volume switch replacement, decomposition method STEP 6]
If you can float the liquid crystal even a little, it is good to insert a pick etc. like the image!
By doing this, the liquid crystal will not close again!
[iPhone7 power button volume switch replacement, decomposition method STEP 7]
Now we will open the gap on the left side.
If you look closely at the inside of the part that could be opened, you will see a black seal or a white seal, but it will peel off regardless because it is a waterproof seal.
[iPhone7 power button volume switch replacement, decomposition method STEP 8]
This time, it is on the right side, but the liquid crystal is floated in the same way as before.
[iPhone7 power button volume switch replacement, decomposition method STEP 9]
A waterproof seal is attached to one lap of the liquid crystal, but please pay attention only around the camera (upper part).
At the moment, I think that I was able to float the liquid crystal of the left and right slightly below, but the upper part does not decompose in the same way because the nail is caught inside, and a little knack is done.
If you pull the liquid crystal lightly in the direction of the arrow, there will be a slight gap between the main body and the liquid crystal, but when the waterproof seal comes into view, please peel off the seal in the gap.
By doing so, it is possible to wake up the LCD panel from the left side to the right side.
[iPhone7 power button volume switch replacement, decomposition method STEP 10]
I was able to open it, but please be careful not to break it because a lot of connectors on the liquid crystal side are connected to the logic board.
[iPhone7 power button volume switch replacement, decomposition method STEP 11]
The first decomposition to be done after opening is work to remove the battery connector from the logic board, but since it is connected under the iron plate of the image, all screws of the red circle part are removed.
Four screws of this part are not Phillips, so please be sure to use a special tool because you can not open it unless you have a Y-shaped screwdriver!
I own several Y-shaped drivers, but I couldn't take them off right away because the sizes were slightly different.
I thought that I would try to disassemble it forcefully as it is, but I am using a special tool because the risk of licking from the experience up to now was high.
[iPhone7 power button volume switch replacement, decomposition method STEP 12]
I was able to remove the iron plate.
I think that it is good to understand the structure of the iPhone7 once in this state.
[iPhone7 power button volume switch replacement, decomposition method STEP 13]
The red arrow part becomes the connector of the battery, but the connector can be removed from the logic board by lifting from the bottom to the top using the tool.
[iPhone7 power button volume switch replacement, decomposition method STEP 14]
Next, the cable on the liquid crystal side is removed, but it decomposes in the same way as the method which removed the connector of the previous battery.
In the previous iPhone series, the connector relationship of the LCD was all gathered on the upper side (upper right), but in the case of the iPhone7, it is one of the changes because it became the lower right!
[iPhone7 power button volume switch replacement, decomposition method STEP 15]
Because there is one more connector under the previous cable, it will also be removed.
[iPhone7 power button volume switch replacement, decomposition method STEP 16]
There is a cable of the camera in this part, but remove the screw attached to the iron plate as if the connector of the liquid crystal was removed.
[iPhone7 power button volume switch replacement, decomposition method STEP 17]
Because there is a connector in the inside when the screw can be removed, it is possible to remove it if it is made to lift from the bottom to the top.
[iPhone7 power button volume switch replacement, decomposition method STEP 18]
Since it was possible to separate the body side and the liquid crystal side of the iPhone7 with this, please keep the liquid crystal side as it is.
After removing the liquid crystal, it is easier to disassemble it if the battery is also removed. Click here to replace the iPhone7 battery
[iPhone7 power button volume switch replacement, decomposition method STEP 19]
Remove the two red-circled screws by using the tool and removing the two red-circled screws.
There is a Wifi cable in the arrow part, but you can easily remove it if you cause it from the bottom to the top.
[iPhone7 power button volume switch replacement, decomposition method STEP 20]
This is the position around the camera and the upper part, but first, all the screws that are enclosed in a red circle are removed.
The screw of the light blue part is on the side, so don't forget to remove it!
[iPhone7 power button volume switch replacement, decomposition method STEP 21]
I think that I was able to remove each plate when I was able to remove the screw of the previous, but there is a connector (orange part) under it, so Remove it from the bottom to the top, and remove all screws that are enclosed in a red circle.
The light blue part has screws on the side, so don't forget to remove it!
[iPhone7 power button volume switch replacement, decomposition method STEP 22]
When you can remove the parts, only one screw is hidden, so remove it.
[iPhone7 power button volume switch replacement, decomposition method STEP 23]
Because there is a small connector next to the camera, I try to wake it up from the bottom and remove it.
The cable part other than the connector is only fixed with double-sided tape, so it will peel off using the tool.
[iPhone7 power button volume switch replacement, decomposition method STEP 24]
I was able to remove the parts!
[iPhone7 power button volume switch replacement, decomposition method STEP 25]
I was able to remove the logic board.
If all screws and connectors are removed, it can be easily removed, but the projection of the sim card part hits and it may be difficult to remove.
In that case, you can easily remove it if you push the protrusion.
[iPhone7 power button volume switch replacement, decomposition method STEP 26]
This part is the back side of the power button, but the screw in the red circle part is removed.
[iPhone7 power button volume switch replacement, decomposition method STEP 27]
If the screw of the red circle part can be removed, the iron plate can also be removed.
[iPhone7 power button volume switch replacement, decomposition method STEP 28]
Since the cable part is fixed to the main body with double-sided tape, it is made to peel off using the tool.
[iPhone7 power button volume switch replacement, decomposition method STEP 29]
This is the volume switch, the manners button side, but let's remove all the screws of the red circle part!
[iPhone7 power button volume switch replacement, decomposition method STEP 30]
The power button and volume switch cable could be removed.
This decomposition method is a decomposition method that is effective when the power button of the iPhone7 does not respond, the volume switch does not work, and is difficult to work.
