Step 1: Open the Google Pixel 4a
Begin by opening the Google Pixel 4a to access the internal components.
The LCD screen must be removed first because it covers the internal components that need to be accessed during the repair.
Step 2: Remove the LCD Screen
Gently heat around the edges of the LCD screen to soften the adhesive securing it to the phone.
A heating pad can be used to warm the display. Alternatively, a heat gun or hairdryer can be used carefully.
Once the adhesive has softened, use a suction cup to lift the screen slightly.
Insert a plastic card pry tool and carefully work around the edges to separate the LCD from the phone body.
Work slowly and avoid inserting the pry tool too deeply, as internal components and the display connection can be damaged.
Once the adhesive has been released, carefully lift the LCD screen away from the phone.
Step 3: Disconnect the LCD
With the LCD screen lifted, remove the LCD connector bracket.
Next, disconnect the LCD connector from the board.
Once the connector is disconnected, the LCD screen can be separated completely from the phone.
Clean the frame edges before continuing with the internal repair.
Step 4: Remove the Mid Frame Plate
Next, remove the mid frame plate.
Carefully take the plate out of the phone to expose the internal components underneath.
Keep the removed screws organized so they can be returned to their original locations during reassembly.
Step 5: Remove the Logic Board Bracket
Remove the logic board bracket to gain access to the components underneath.
Carefully release the bracket and set it aside.
Step 6: Remove the Front Camera and Headphone Jack
Next, remove the front camera and headphone jack.
Carefully disconnect and remove the front camera assembly and headphone jack from the phone.
Set both components aside safely while continuing with the repair.
Step 7: Remove the Speaker
Remove the speaker from the phone.
Handle the speaker carefully and place it somewhere safe while the logic board is being removed.
Step 8: Remove the Logic Board
The logic board must now be removed to access the faulty power and volume assembly.
Disconnect the required connections from the board.
Carefully remove the screws securing the logic board and lift the board out of the phone.
Handle the logic board gently and avoid putting unnecessary pressure on its components or connectors.
Step 9: Remove the Faulty Power and Volume Assembly
With the logic board removed, the non-working Google Pixel 4a power and volume assembly can be accessed.
Carefully remove the faulty power and volume component from the phone.
Take care during removal to avoid damaging surrounding components.
Step 10: Install the New Power and Volume Assembly
Position the replacement Google Pixel 4a power and volume assembly in the correct location.
Secure the new component and make sure it is properly positioned before continuing with reassembly.
Step 11: Reinstall the Logic Board
Place the logic board back into the phone.
Carefully position the board and reconnect the required connections.
Secure the logic board and make sure it sits correctly in the housing.
Step 12: Reinstall the Speaker
Place the speaker back into its original position.
Make sure it is properly seated before continuing with the reassembly.
Step 13: Reinstall the Headphone Jack and Front Camera
Place the headphone jack and front camera back into their respective positions.
Reconnect and secure both components before continuing.
Step 14: Reinstall the Logic Board Bracket
Place the logic board bracket back into position.
Secure the bracket and make sure it is correctly aligned with the surrounding components.
Step 15: Reinstall the Housing and Mid Frame Plate
Next, reinstall the housing and mid frame plate.
Make sure the frame components are properly aligned and securely positioned before continuing with the LCD installation.
Step 16: Reinstall the LCD Screen
Before installing the LCD screen, make sure the frame edges are clean and the display is properly aligned.
Carefully place the LCD screen back onto the phone.
Apply gentle pressure around the edges so the display sits securely against the phone body.
If new adhesive is required, use suitable LCD adhesive to secure the screen.
Step 17: Close and Complete the Installation
Complete the final assembly of the Google Pixel 4a.
Make sure the LCD screen is firmly attached and properly aligned before finishing the repair.
Once the phone is fully assembled, test the power and volume buttons to confirm that they respond correctly.
End of Repair Guide
The Google Pixel 4a power and volume button replacement is now complete. After the phone has been fully reassembled, test the power button and both volume controls to make sure they are functioning correctly.
