Studio Display XDR Logic Board

Before You Begin

Danger

Ensure that the AC power cord isn’t plugged into an electrical outlet.

Caution

This procedure requires System Configuration. To perform System Configuration you will need the following:

  • The latest version of Apple Service Utility installed on an Apple silicon or Intel-based Mac with the Apple T2 Security Chip running macOS Sonoma 14.1 or later

  • Internet access

  • A USB-C charge cable or a USB-A to USB-C cable. The USB-C cable must support both power and data. Don’t use Thunderbolt 3 cables.

Remove the following parts before you begin:

Tools

  • Adjustable torque driver (0.3–1.2 Nm)

  • Adjustable torque driver (10–34 Ncm)

  • ESD-safe tweezers

  • Nylon probe (black stick)

  • Torx Plus 5IP 50 mm bit

  • Torx Plus 6IP 25 mm bit

  • Torx Plus 8IP 25 mm bit

Refer to a full list of tools required for all repairs.

Removal

Note: If you’ve already completed the removal steps, skip to reassembly.

  1. Use ESD-safe tweezers to peel the polyester film tab away from the left fan flex cable connector.

  2. Use ESD-safe tweezers to flip up the locking lever on the left fan flex cable connector. Then slide the end of the flex cable out of the connector.

  3. Use ESD-safe tweezers to peel the polyester film tab away from the right fan flex cable connector.

  4. Use ESD-safe tweezers to flip up the locking lever on the right fan flex cable connector. Then slide the end of the flex cable out of the connector.

  5. Pinch both sides on the end of the right speaker flex cable. Then slide the flex cable out of the connector.

  6. Pinch both sides on the end of the left speaker flex cable. Then slide the flex cable out of the connector.

  7. Use the flat end of the black stick to press and hold the ”PUSH“ button on the zero-insertion force (ZIF) microphone flex cable connector. While pressing the button, slide the end of the ZIF microphone flex cable out of the connector.

  8. Use ESD-safe tweezers to peel the polyester film tab away from the ambient light sensor (ALS) flex cable connector. Then use ESD-safe tweezers to flip up the locking lever on the ALS flex cable connector. Then slide the end of the flex cable out of the connector.

  9. Use ESD-safe tweezers to peel the polyester film tab away from the power supply signal flex cable connector on the logic board.

  10. Use ESD-safe tweezers to flip up the locking lever on the power supply signal flex cable connector on the logic board. Then slide the end of the flex cable out of the connector.

  11. Use the 0.3–1.2 Nm adjustable torque driver and 6IP bit to remove the four 6IP screws (923-14057) from the bus bar. Then remove the bus bar and save it for reassembly.

  12. Use the 0.3–1.2 Nm adjustable torque driver and 8IP bit to remove the six 8IP screws (923-14042) from the logic board.

  13. Use the 10–34 Ncm adjustable torque driver and 5IP bit to remove one 5IP screw (923-14059) from the logic board.

  14. Lift the logic board out of the housing while using a black stick to keep all the cables clear.

    • Caution: Keep all cables clear to avoid damaging the cables.

Reassembly

  1. Lower the logic board into the housing while using the black stick to keep all cables clear. Align the screw holes on the logic board with the screw holes in the housing.

    • Caution: Keep all cables clear to avoid damaging the cables.

  2. Set the torque value on the 10–34 Ncm adjustable torque driver to 16 Ncm. Use the adjustable torque driver and 5IP bit to reinstall one 5IP screw (923-14059) into the logic board.

  3. Set the torque value on the 0.3–1.2 Nm adjustable torque driver to 1.15 Nm. Use the adjustable torque driver and 8IP bit to reinstall the six 8IP screws (923-14042) into the logic board.

  4. Slide the end of the power supply signal flex cable into the connector on the logic board. Flip down the locking lever on the connector. Then press the polyester film tab onto the end of the flex cable.

  5. Slide the end of the ALS flex cable into the connector. Flip down the locking lever on the connector. Then press the polyester film tab onto the end of the flex cable.

  6. Slide the end of the microphone flex cable into the connector.

  7. Slide the end of the left speaker flex cable into the connector.

  8. Slide the end of the right speaker flex cable into the connector.

  9. Slide the end of the right fan flex cable into the connector. Flip down the locking lever on the connector. Then press the polyester film tab onto the end of the cable.

  10. Slide the end of the left fan flex cable into the connector. Flip down the locking lever. Then press the polyester film tab onto the end of the flex cable.

  11. Position the bus bar on the logic board, aligning the hooks on the bus bar with the notches on the logic board.

  12. Set the torque value on the 0.3–1.2 Nm adjustable torque driver to 0.45 Nm. Use the adjustable torque driver and 6IP bit to reinstall the four 6IP (923-14057) screws into the bus bar.

Reinstall the following parts to complete reassembly:

Repair Completion

Caution

System Configuration is required if you replaced the logic board. You will initiate and complete System Configuration at the end of display reassembly. You will need a separate Mac with Apple Service Utility installed to perform System Configuration.
