REPAIR TIME & SKILL LEVEL:

This repair is estimated to take about 1 to 1.5 HOURS to complete and is of INTERMEDIATE difficulty, requiring careful handling of flex cables, use of specialized screwdrivers, and basic disassembly skills.

STEPS:

Tools You Need

For this repair, you will need a smudging tool, a heating mat set to about 40°C, a replacement screen, isopropyl alcohol, a tri-wing screwdriver, a pentalobe screwdriver, a Phillips screwdriver, and optionally an air blower tool for cleaning dust. A heating gun can be used instead of a heating mat, though the mat offers more control.

---

Remove Pentalobe Screws & Begin Heating

• Use a pentalobe screwdriver to remove the bottom screws of the iPhone 11 Pro Max.
• Set your heating mat to about 40°C to help loosen the screen adhesive.
• Note that this phone uses less adhesive than newer IP68-rated models, making opening a bit easier.

---

Disconnect Battery for Safety

• Use a tri-wing screwdriver to remove the bracket that protects the battery flex cable.
• Disconnect the battery flex cable to prevent powering the phone during the repair.
• This is a critical safety step to avoid short circuits during component removal.

---

Remove Display Shield Plate

• Remove the plate secured by six tri-wing screws to access the main display connections.
• These include the LCD, digitizer, and proximity sensor flex cables.
• Carefully set aside the plate and screws to keep them organized for reassembly.

---

Disconnect Flex Cables

• Use a plastic tool to lift up the LCD, digitizer, and proximity sensor flex cables.
• Be gentle to avoid damaging the cables, which are vital for display functionality.
• The right side of the phone houses the flex cables, so avoid inserting tools too deep.

---

Gently Remove the Screen

• Carefully lift the screen once cables are detached, using a spudging motion rather than prying.
• Avoid cracking the screen, especially if you plan to recycle it.
• This step requires patience and control to avoid cable damage.

---

Clean Dust and Debris

• Use a compressed air tool to blow away any internal dust or debris.
• Pay attention to the proximity sensor area, which often accumulates dust that affects audio quality.
• Cleaning here helps maintain a professional repair standard and improves audio clarity.

---

Free the Proximity Sensor

• Use a Phillips screwdriver to remove the proximity sensor from the old screen.
• Set the screen back on the heating mat briefly to soften the adhesive under the sensor.
• Carefully lift the proximity sensor, taking care not to tug on the ribbon cables.

---

Replace or Clean Sensor Components

• Replace the plastic on the proximity sensor if it’s worn or dirty, as done in the video.
• Blow out any dust trapped in the sensor or earpiece area.
• These steps enhance call quality and help deliver a clean, professional result.

---

Reconnect Display Components

• Reattach the LCD, digitizer, and proximity sensor cables in reverse order.
• Take your time to align each cable properly and press gently into place.
• Leave the battery cable disconnected until all other components are secured.

---

Reinstall Display Shield Plate

• Place the shield plate back over the flex cables.
• Secure it with the six tri-wing screws removed earlier.
• This adds structural support and protects delicate connections.

---

Reconnect Battery & Final Assembly

• Reconnect the battery flex cable as the final step before sealing the screen.
• Reattach the battery bracket with the tri-wing screw.
• Carefully align and press the screen back into place on the device frame.

---

Test Functionality

• Power on the device to check that the touchscreen responds correctly.
• Verify that the proximity sensor and display work as expected.
• If all looks good, the repair is complete and the phone is ready for use.
