A Step-By-Step Guide On Replacing An iPhone 7 Screen
Step 1. Book In Your Repair
When repairing your iPhone with iMend.com, you have two options. You can either mail-in your phone to one of our repair centre of get your device fixed at the comfort of your own home by one of our nationwide technicians.
When booking an iPhone 7 screen replacement, you will receive a brand new AAA screen made up of Glass (digitizer), LCD and touchscreen.
Step 2. Initial iPhone Inspection
First things first, the technician will need to establish the level of damage the screen has gained. The frame is also inspected, making sure there are no dents or bends. If you were to try and replace the screen without checking this important procedure, the new screen may not sit flush.
Step 3. Removing Bottom Screws and Screen
Slowly and carefully remove the two bottom screws either side of the charging port, loosening the screen.
Once the screen has started to loosen, the tech will use a suction cup on the lower part of the screen (near the home button) or an iSesamo tool to ease open the gap between the screen and the case.
Insert the spludger in between the gap, gently splitting the adhesive. Ease around the left side of the phone separating the case and the screen, then repeat on the right hand side.
Slightly lift the bottom of the screen, this will pop the clips holding in the rear case.
Finally, Open up the iPhone by lifting the left side of the assembly. Similar to opening a book.
Step 4. Disconnecting The Battery
Once you have lifted the screen of the iPhone 7, it’s time to disconnect the battery. Start by removing the four screws holding on the lower connector bracket. This bracket should now be removed. One of the screws will be longer then the others.
Lay your screws in order. Putting the wrong screws back in the wrong holes will lead to long screw damage essentially piercing and inevitably breaking the motherboard.
Use your plastic spludger to disconnect any FPC connectors. This removes all power from the phone. Be gentle, you can remove the socket from the motherboard, breaking your battery connector.
Step 5. Removing Display Assembly
There are two 1.3mm screws at the top of the device. Slowly remove these screws and remove the front panel bracket, revealing the front panel sensor assembly.
Disconnect the front panel sensor assembly from the logic board with a plastic spludger. You should now be able to remove the display assembly. Once again, be gentle when trying to disconnect the sensor assembly as with too much force you could remove the socket to the logic board.
Step 6. Removing Home Button/Touch I.D
Remove three 1.3mm screws and 1.1mm screw behind the home button. Ensure all of the screws are in order to prevent long screw damage when assembling the mobile back together. Remove the bracket that secures the home button.
Use your plastic spludger to lift the home button connector to disconnect it from it’s socket. Once again, be very gentle when lifting the connector. Too much force will disable the touch sensor.
Once again use your spludger but this time move the underlying connector away from the home/touch ID button. To prevent damage apply heat allowing the component to become supple.
Step 7. Remove Earpiece Speaker
Remove the two 2.6mm screws and one 1.7mm screws and proceed to remove the bracket with your tweezers. Use the tweezers to lift the front camera out of the way allowing you to reach the earphone speaker.
You will see two screws either side of the silver panel. Both screws are different sizes so make sure that the 1.9mm screw goes back into the left hand side screw hole and the 2.5mm screw goes back into the right hand side, otherwise long screw damage can occur. Use your tweezers to remove the earphone speaker.
Step 8. Remove Front Camera and Sensory Cable
Start by using your plastic spludger to gently lift your ambient light out of the recess of the front panel. Place your iPhone back onto the heat plate. The adhesive will now be easier to break. Place your pick under the front camera housing and slowly slide towards the screw posts.
Once you get close to the screw posts, start to lift the cable with your pick popping the two plastic posts removing it from the last part of the adhesive. The front camera and sensory cable will now be safe to remove.
Step 9. Remove LCD Shield Plate
There are three screws both sides of the display assembly. Make sure they are in a distinctive place away from other screws. Once again, use your heat tray to warm the adhesive.
Use the pick and slowly slide and break the adhesive, starting at the corner near the home button and moving across. Once you have broke the adhesive, slowly lift the LCD shield plate. Be extremely careful as you can snag the display data cables if not done correctly.
Step 10. Reattaching LCD Shield
Once the device is cleaned, the LCD backplate should be reattached with the same six screws previously used.
Step 11. Re-Installing Home Button/Touch I.D.
Re-installing the home button is one of the hardest parts of the repair. It takes a lot of care and precision. The technician then checks the feel of the home button ensure it is the best fit.
Step 12. Transplanting the Earpiece Speaker, Front Camera, Sensory Cable and Flex Assemblies
The flex from the previous screen is transplanted onto the new screen. The flex helps the camera sit perfectly in the phone assembly. The flex for the sensory and front camera is first, placed in between the plastic gasket helping align up the sensory cable.
Once the cable is fitted, the front camera should still be well out of the way of the earphone speaker.
Next, screw the earphone speaker back into place using the exact same screws. Once the earphone speaker is fitted, the camera can can now bend back into place.
Step 13. Reattach Sensory panel
Carefully place the sensory connectors back onto the logic boards. Do not push from the centre as the can bend with ease, which can result in a black screen of strips on the LCD
Step 14. Screen Test
The tech will then test to see if the screen is fully functioning. The screen is turned on, and test for blemishes such as dead pixels. This is usually tested by dragging an app around the screen to identify any issues with the screen.
Step 15. Reconnect PCB Connectors
After all of screen test checks are complete, it is safe to connect the PCB connectors. Similar to the sensory connectors, you must be careful reconnecting the connectors as they are easy to bend and ultimately ruin.
Fix the bracket back into place using the correct screws.
Step 16. Fix The New Screen
It’s now time to put back the screen into placing popping the screen into the location clips. Once this is completed, insert the two screws into the holes either side of the charging port.
