Sony Xperia Z Tear Down Guide:​

Before getting started with the repair you will need to first totally power down your device.

Begin by using a heat gun (on low) or a blow dryer (on medium) warming the sides and edges of the back cover in order to loosen the adhesive holding the back cover to the device.

Next firmly place a Suction Cup Tool on the back cover near the top right. This will help with removing the back cover, along with using a safe open pry tool. While pulling on the suction cup run the pry tool along the edges loosening the adhesive until you are able to remove the back cover. Additional heating may be required.

​

Following the removal of the back cover the internal components are exposed. First you will need to release the battery connection (highlighted in red below in figure 2.1) and the flex cable it is attached to.

The battery itself is held in place with strong adhesive, it is important to note the yellow and blue highlighted areas in the figure (2.1) below. These areas show where the flex cables (in yellow) and the adhesive (in blue) are located underneath the battery. Be sure to avoid prying where the flex cables are positioned, and use a Spudger tool to remove the battery from the adhesive.

After the battery is removed you will release a few flex cables (4) as well as a plastic spacer (highlighted in green below in figure 2.2)

Next, using the Spudger tool remove the vibrate motor (highlighted in purple) located at the bottom right of the device.

Then you will unscrew the four (4) Small Phillips screws (highlighted in red in figure 2.2) using a Small Phillips screwdriver. Once the screws are unscrewed, release the housing (in purple) on the top right side of the unit using your pry tool.

​

Now we will continue to remove some more of the smaller components.

(Figure 3.1) Remove the main camera which is covered with copper tape. Release the tape and pop connector to remove the camera.

(Figure 3.2) Remove the front camera by releasing the pop connector.

(Figure 3.3) Remove the sim card. Using tweezers will most effectively help release the sim card tray.

(Figure 3.4) Remove the motherboard. Be careful not to tear or rip any of the loose released connections while removing the motherboard.

​

(Figure 4.1) Using a Small Flathead screwdriver remove the ear speaker.

(Figure 4.2) Remove the headphone jack and sensor flex cable with your pry tool.

(Figure 4.3) Also with the pry tool, release the small plastic cover located at bottom right of the device. Cautiously release this part because it is attached to the antenna flex cable.

(Figure 4.4) To release the antenna flex cable release the circuit board it is attached to. With the pry tool release the circuit board from the clips in the housing.

​

Use your pry tool to complete these tasks.

(Figure 5.1) Release the lower flex cable.

(Figure 5.2) Release the final circuit board (for the antenna).

(Figure 5.3) Release the side button flex cable with mic. Begin at the lower left corner and work your way up. Be very careful during this step as the flex cable is very delicate.

(Figure 5.4) Remove the metal bracket which holds the button housing. Next remove the side button flex cable by separating it from the adhesive.

​

The following step will be to remove the screen from the front housing.

(Figure 6.1) Once again use a heat gun (on low) or a blow dryer (on medium) and heat the corners and sides of the screen assembly for about 45 - 60 seconds.

(Figure 6.2) Removing the screen assembly can be difficult with this device. After the adhesive has been warmed use your pry tool to begin removing the screen. The easiest place to start is at the top of the device where you can pry between the speaker hole and the camera hole. Because the adhesive is so strong the glass screen will most likely crack during this process.

Switch to your Spudger tool in order to gain more leverage underneath the screen. Also apply more heat if needed.

(Figure 6.3) Continue to pry underneath the adhesive and work your way around until you can release the touch screen and LCD combination screen.

(Figure 6.4) Remove the final flex cable from the housing.

​

Lastly, install the new parts while discarding the damaged parts and simply reverse these steps in order to reassemble your device.
