Before You Begin: Important Safety Tips

⚠️ Power Off Your Device: Always turn off your iPhone completely before starting any repair.

⚠️ Battery Precaution: Be extremely careful not to puncture or bend the battery during the repair process.

⚠️ Work Area: Use a clean, well-lit workspace with an anti-static mat if possible.

⚠️ Organize Screws: Keep screws organized by step - they're different sizes and must go back in the correct locations.

Step-by-Step iPhone 15 Pro Max LCD Screen Replacement

Step 1: Power Down and Prepare (5 minutes)

  1. Back up your iPhone to iCloud or your computer
  2. Power off your iPhone 15 Pro Max completely
  3. Remove your SIM card tray using the SIM ejector tool
  4. Clean your workspace and lay out all tools
  5. Put on anti-static wrist strap if available

Step 2: Remove the Bottom Screws (2 minutes)

  1. Locate the two Pentalobe screws at the bottom of the iPhone (next to the charging port)
  2. Use the P2 Pentalobe screwdriver to remove both screws
  3. Keep these screws safe - they're easy to lose!

Pro Tip: Use a magnetic mat or small containers to organize screws by step.

Step 3: Heat and Separate the Display (10 minutes)

  1. Apply heat around the edges of the screen using a heat gun or hair dryer (60-80°C / 140-176°F)

    • Focus on the edges for 2-3 minutes
    • Don't overheat - the goal is to soften the adhesive

  2. Place suction cup near the bottom of the screen (avoid the camera area)

  3. Apply steady pressure and pull up gently while inserting a plastic pick into the gap

  4. Slide the pick around the edges to separate the adhesive

    • Start at the bottom
    • Work your way around the sides
    • Be careful near the top (Face ID sensors)

  5. Don't fully remove the screen yet - it's still connected by cables!

⚠️ Warning: Do NOT open the screen more than 90 degrees - the cables are still attached!

Step 4: Disconnect the Battery (5 minutes)

  1. Open the screen to about 90 degrees and prop it up with a box or stand

  2. Remove the metal bracket covering the battery connector

    • Use Y000 Tri-point screwdriver
    • Keep screws organized

  3. Disconnect the battery connector using a spudger

    • Gently pry up from the bottom
    • This prevents electrical shorts during repair

Safety First: Always disconnect the battery before disconnecting any other cables!

Step 5: Disconnect Display Cables (5 minutes)

  1. Remove the metal bracket covering the display connectors

    • Usually 4-5 Y000 screws
    • Keep track of screw positions

  2. Disconnect three display cables:

    • OLED display connector
    • Digitizer connector
    • Front sensor assembly connector

  3. Use a spudger to gently pry each connector straight up

  4. Remove the old screen and set it aside safely

Step 6: Transfer Components to New Screen (10 minutes)

Components to transfer from old screen:

  1. Earpiece speaker

    • Remove screws holding the bracket
    • Carefully lift out the speaker
    • Transfer to new screen

  2. Front camera and sensor assembly

    • Remove screws
    • Disconnect any cables
    • Transfer carefully (contains Face ID - handle with care!)

  3. Home button/Touch ID (if applicable)

    • This is paired to your phone
    • Must be transferred for Touch ID to work

⚠️ Critical: The Face ID module is extremely delicate. Handle with extreme care!

Step 7: Install the New LCD Screen (5 minutes)

  1. Connect display cables to the new screen in reverse order:

    • Front sensor assembly connector
    • Digitizer connector
    • OLED display connector

  2. Reconnect the battery temporarily to test

  3. Test the new screen:

    • Power on the device
    • Check touch response
    • Test Face ID
    • Check display quality
    • Test all buttons

  4. If everything works, power off and disconnect battery again

Step 8: Secure and Seal (5 minutes)

  1. Replace the metal brackets over the connectors

    • Tighten all screws (don't overtighten!)

  2. Reconnect the battery permanently

  3. Apply new adhesive strips around the edges of the frame

    • Remove old adhesive residue first
    • Apply evenly for waterproofing

  4. Carefully align the screen with the frame

  5. Press firmly around all edges to seal

    • Start from the top
    • Work your way down
    • Apply even pressure

  6. Replace the two bottom Pentalobe screws

Step 9: Final Testing and Quality Check

  1. Power on your iPhone

  2. Test all functions:

    • ✅ Touch sensitivity across entire screen
    • ✅ Face ID recognition
    • ✅ Front camera
    • ✅ Earpiece speaker
    • ✅ Proximity sensor
    • ✅ Ambient light sensor
    • ✅ Display brightness and colors
    • ✅ 3D Touch/Haptic Touch

  3. Check for issues:

    • No backlight bleeding
    • No touch dead zones
    • Proper color reproduction

Troubleshooting Common Issues

Problem: Screen doesn't turn on

  • Check all cable connections are secure

  • Try a hard reset (Volume Up, Volume Down, hold Power)

Problem: Touch not working

  • Reconnect digitizer cable
  • Check for debris in connector
  • Ensure screen is genuine quality part

Problem: Screen separating from frame

  • Apply new adhesive strips

Post-Repair Care Tips
