How to Fix Not Connected Camera in MacBook 2025

Issue Description

A MacBook has arrived for repair with a camera issue, showing the “No Connected Camera” error. However, we will demonstrate an alternative repair method to fix the camera without replacing the screen.

Background

The device was initially brought to a Local repair store, but they were unable to fix the issue. i inspection, we noticed that attempts had already been made to repair the MacBook camera’s flex cable, but the issue persisted. Our diagnosis reveals that the real problem lies in the power rail of the camera, specifically the burnt-out inductor inside it.

Step-by-Step Repair Guide

Step 1: Opening the PCB

• Unlike the conventional method of opening the PCB entirely, which is time-consuming, we will take a shortcut method.
• The inductor in question is directly connected to the 5V rail, so rather than fully opening the PCB, we will replace the inductor externally.

Step 2: Replacing the Burnt-Out Inductor

1. Obtain a Replacement Inductor
   • We will source a working inductor from a scrap board.
   • The inductor needs to match the original specifications for optimal power flow.
2. Connecting the New Inductor
   • The inductor will be connected directly to the 5V rail.
   • A jumper wire will be borrowed from another section of the board to complete the circuit.
   • This method avoids the need for an extensive PCB teardown, saving time.

Step 3: Running a Jumper Wire to the Camera Flex Cable

• Instead of routing a wire through the back end of the PCB, we will directly connect the jumper wire to the flex cable of the display.
• This approach is much more efficient and allows us to repair the camera in just 10-15 minutes.

Step 4: Applying UV Mask for Protection

• Since we have installed an external inductor, UV masking is necessary to protect the circuit.
• The UV mask needs to be dried properly to secure the connection.

Step 5: Connecting the Battery and Charger

• After ensuring the repair is completed, we will reconnect the battery flex cable.
• Since the MacBook does not turn on without power, the charger must also be connected.

Step 6: Testing the Camera

• We start the camera application to check if the issue has been resolved.
• The camera is now fully functional, confirming that the repair was successful.

Why This Method Works

• The issue was due to a burnt power rail rather than a display failure.
• Water damage is a common cause of power rail failure, as high current causes the inductor to burn out first.
• Signals remain intact, meaning replacing the inductor restores full camera functionality.
• Running a jumper wire directly on the flex cable saves time compared to full PCB disassembly.
• The method is cost-effective, avoiding unnecessary screen replacements.

Final Thoughts

• This repair technique is a permanent solution for water-damaged camera issues in MacBooks.
• If you experience a similar issue, always check the power rails first before considering screen replacement.
• Following this method allows for a quick and reliable fix, saving both time and money.

By using proper micro-soldering techniques and understanding power rail distribution, anyone with the right tools can effectively repair a MacBook’s camera without replacing the entire screen.
