How to iPhone 5 Audio Control and Power Button Cable Replacement

Introduction

Use this guide to replace the single cable that connects to the ringer switch, power button, and volume buttons.

Step 1 Display Assembly

If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass.
Lay overlapping strips of clear packing tape over the iPhone's display until the whole face is covered.
This will keep glass shards contained and provide structural integrity when prying and lifting the display.

Wear safety glasses to protect your eyes from any glass shaken free during the repair.

Step 2

Before disassembling your iPhone, be sure it is powered off.
Remove the two 3.6 mm Pentalobe screws next to the Lightning connector.

Step 3

In the following steps you will be pulling the display up out of the phone body. The display is composed of a glass screen and a plastic bezel with metal clips.

Regardless of the tool you use, you need to be sure you pull up the entire display.

If the glass begins to separate from the plastic, as shown in the first image, slide a plastic opening tool between the plastic frame and the metal phone body to pry the metal clips out of the case.





If you are reassembling a phone with a separated display bezel, you may want to place a thin strip of adhesive between the plastic bezel and the glass to keep the phone closed.

Step 4

Make sure the suction cup is firmly attached to the front panel assembly.
While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case.

Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.

With a plastic opening tool, begin to gently pry the rear case down, away from the display assembly, while you pull up with the suction cup.
There are several clips attaching the front panel assembly to the rear case, so you may need to use a combination of the suction cup and plastic opening tool to free the front panel assembly.

Step 5

Do not try to completely remove the front panel assembly from the rear case, as there are several ribbon cables still attached at the top of the iPhone.

Once the clips have been released on the bottom and sides of the front panel assembly, pull the bottom of the assembly away from the rear case.

Open the display to about a 90ยบ angle, and lean it against something to keep it propped up while you're working on the phone.

Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.

Step 6
Remove the following two screws securing the metal battery connector bracket to the logic board:
One 1.8 mm Phillips screw

One 1.6 mm Phillips screw

Step 7


Remove the metal battery connector bracket from the iPhone.

Step 8

Use a plastic opening tool to gently pry the battery connector up from its socket on the logic board.


Be very careful to only pry up on the battery connector and not the socket on the logic board. If you pry up on the logic board socket, you may break the connector entirely.


Remove the following screws securing the front panel assembly cable bracket to the logic board:
Two 1.2 mm Phillips screws
One 1.6 mm Phillips screw

This screw tends to not be attracted to a magnetized screwdriver. Take care not to lose it when removing, and make sure it gets back into the right place—a magnetized screw may interfere with the compass.

Lift the display cable bracket toward the battery to unhook it, and remove it from the iPhone.
During reassembly, clip the left-hand hooks under the logic board and lower the bracket towards the outside of the phone.



Use a plastic opening tool to disconnect the three front panel assembly cables:
Front-facing camera and sensor cable
LCD cable
Digitizer cable

When reassembling your phone, the LCD cable may pop off the connector. This can cause white lines, or nothing at all to appear when powering your phone back on. If that happens, simply reconnect the cable and power cycle your phone. The best way to power cycle your phone is to disconnect and reconnect the battery.

Use the plastic opening tool to gently pry the battery up, only at the outside edge of the phone. Prying anywhere else, especially near the logic board, may result in damage to the logic board.
If the battery doesn't pry easily out of the case, reheat and reapply the iOpener and try again.
Pry gently and evenly to avoid deforming the battery. A bent battery can be a fire hazard.

Do not pry at the top portion of the battery, you risk severing the volume control cables.

Remove the battery.
During reassembly, make sure the battery is seated firmly against the rear case. This will prevent any damage to other components when reinstalling the front panel assembly.

Perform a hard reset after reassembly. This can prevent several issues and simplify troubleshooting.
