    Do you have a Sony Xperia Z with a cracked or broken screen? This in depth guide will take you through how to disassemble the Sony Xperia Z and restore a damaged touch screen, LCD screen, or any internal components.

    This guide will aid in the installation of the following Sony Xperia Z part(s):

    • Sony Xperia Z LCD + Touch Screen Assembly Replacement
    • Other Internal Components

    Essential Tools:

    • Safe Open Pry Tool
    • Spudger Tool
    • Small Phillips Screwdriver
    • Small Flathead Screwdriver
    • Suction Cup Tool
    • Adhesive Strips
    • Tweezers
    • Heat Gun/Blow Dryer

    Sony Xperia Z Take Apart Guide:

    • Prior to beginning the repair you will need to fully power off your device.
    • Start with using a heat gun (on low heat) or a hair dryer (on medium heat) heating up the sides and corners of the back cover so that the adhesive loosens which holds the back cover to the entire device.
    • Then securely place a Suction Cup Tool onto the back cover. The most effective spot for the suction cup to be placed is near the top right. This along with a safe open pry tool will aid with an easier removal of the back cover. Pull on the suction cup and run the pry tool along the sides which loosens the adhesive to the point where you can remove the cover. During the removal you may encounter stubborn areas where the adhesive is tougher. Simply re-heat the adhesive to loosen it.

    • Once the back cover has been removed it exposes the internal parts. Now you can release the battery connection (highlighted in red in figure 2.1) and the flex cable is also attached.
    • You will find the battery is held in it's housing with strong adhesive. At this point it is helpful to note the yellow and blue highlighted areas (figure 2.1) depicted in the picture below. The highlighted areas indicate where the flex cables (yellow) and the adhesive (blue) are positioned beneath the battery. Make sure not to pry where the flex cables are located. Using the Spudger tool will make it much easier to release the battery from the adhesive.
    • Following the removal of the battery you will need to release a four (4) flex cables along with a plastic spacer (all parts are highlighted in green in figure 2.2).
    • Using your Spudger tool take out the vibrate motor, which is highlighted in purple and is at the bottom right of the unit.
    • Next unscrew the Small Phillips screws (4) using a Small Phillips screwdriver (screws are highlighted in red in figure 2.2). After the screws are removed, release the small black housing (highlighted in purple) on the top right of the device using the pry tool.

    • For the next step we continue to remove more of the internal components.
    • *Figure 3.1* Remove the main camera which is held in place with copper colored tape.
    • *Figure 3.2* Release the pop connector and remove the front camera.
    • *Figure 3.3* Using a pair of tweezers remove the sim card tray.
    • *Figure 3.4* While being cautious not to rip or tear any of the released connections remove the motherboard.

    • *Figure 4.1* Remove the ear speaker using a Small Flathead screwdriver.
    • *Figure 4.2* With your pry tool remove the headphone jack and sensor flex cable.
    • *Figure 4.3* Release the plastic cover located at bottom right of the device with your pry tool. Be careful when releasing this part due to the fact it is attached to the antenna flex cable.
    • *Figure 4.4* Release the circuit board that is attached to the antenna flex cable. Using your pry tool release the circuit board from the clips holding it to the housing.

    • For the following steps use your pry tool.
    • *Figure 5.1* Release the lower flex cable at the bottom right side of the device.
    • *Figure 5.2* Release the last antenna circuit board.
    • *Figure 5.3* Release the side button flex cable. Start at the lower left corner and run the tool upwards under the cable. You should be cautious during this step because the flex cable is very fragile.
    • *Figure 5.4* Remove the metal bracket that holds the cable to the housing. Then completely remove the side button flex cable from the adhesive.

    • The overall last step will be to remove the screen from the front housing.
    • *Figure 6.1* Use the heat gun (low) or blow dryer (medium) and warm the corners and sides of the screen assembly for around 45 seconds - 1 minute.
    • *Figure 6.2* Taking off the screen assembly can be troublesome with this device. Once the adhesive has been heated use the pry tool and start removing the screen. The best place to begin is at the top of the device where you can shim in between the speaker hole and the camera hole. Being that the adhesive is very strong the glass touch screen will likely crack or shatter during this step.
    • Use the Spudger tool to gain leverage beneath the screen. Apply more heat where it is applicable.
    • *Figure 6.3* Continue to pry underneath the adhesive and work your way around the edges and sides until you are able to release the touch screen and LCD combination screen.
    • *Figure 6.4* Remove the last flex cable.

    • Finally, replace the old damaged parts with the news parts and reverse these steps in order to put your device back together.

    cracked screen likes this.
  5. quick question, my phone is currently in the hands of sony's approved uk repair centre, what is the link between these cracking and needing a new battery? I've seen many people mention needing a new battery but no one is sure why. It was suggested to me on Friday (by Xperia support) that the battery is connected/joined to the rear screen and that is why, but he was going to look into my repair.

    cracked rear screen = a new battery, a new ear piece, new case, new cover. but no one can tell me why.

    Thanks dave

    It's really hard to determine. But if it happens to be true it gotta be very rare.

    Hello,

    the broken screen of my Xperia Z was replaced by a workshop (whole assembly with frame).
    Now cell phone reception is much worse than before. It still works, but in areas with low cell phone signal I have no contact now, I had contact before the repair was carried out.

    Do you know reason and solution for the problem?

    Thanks, Michael

    Hello and welcome to the forums. You say a workshop did the repairs . First did you have working signal before the screen breakdown .

    Yes, I had normal signal before screen breakdown and with broken screen as well (used it with a mouse and USB-OTG).
    I guess something went wrong during reassembling...

    Take/send it back to the workshop, explaining the problem, and suggest that they check the that antenna is connected correctly. It's possible that one of the flex connectors has been missed or damaged during reassembly.

    That is what you should do. Sounds like the workshop has mad a mistake and did not connect something or has just broke a cable that is not allowing the device to be in working order.
