Repairing a USB camera module usually involves the following steps:
Primero, troubleshooting
Connection check:
Make sure that the USB camera module is securely connected to the computer, without any looseness or poor contact.
Try replacing the USB cable or USB port to rule out connection cable or port faults.
Power supply check:
If the camera module has an external power supply, check whether the power adapter is working properly.
Observe the power indicator light on the camera module to ensure that the power supply is normal.
System identification
In the Windows system, open the Device Manager (right-click the “Start” menu and select “Device Manager”), and check whether the camera module is displayed under “Image Devices” o “USB Video Devices”.
Pay attention to whether there is a yellow exclamation mark or question mark in the device manager. This usually indicates a driver issue or the device is not identified correctly.
Second, driver update and setting adjustment
Driver update:
Visit the official website of the camera module manufacturer and download the latest version of the driver.
Install the driver according to the guidelines provided by the manufacturer and restart the computer to apply the changes.
System Settings adjustment
Make sure that the camera Settings of the operating system do not disable the camera module.
In the privacy Settings, check whether the application is allowed to access the camera.
If a third-party camera software is used, make sure the software Settings are correct and the camera module is not disabled.
Third, hardware inspection and maintenance
Visual inspection:
Check whether the casing of the camera module is damaged or deformed, and whether the lens is clean and free of stains.
Gently shake the camera module and listen for any internal loosening sounds. This may indicate that the internal components are damaged.
Internal inspection:
If you have electronic repair skills, you can open the casing of the camera module (note to disconnect the power supply before operation) and check if there are any signs of charring, cracking or corrosion on the internal circuit board.
Check whether the internal connection wires of the camera module are loose or broken.
Professional maintenance
If the above steps fail to solve the problem or if you lack electronic repair skills, it is recommended that you contact the manufacturer or a professional repair center for inspection and repair.
Note that it is best to back up the important data in the camera module (if applicable) before sending it for repair.
Fourth, testing after maintenance
Connection test
Reconnect the repaired camera module to the computer and make sure the connection is stable.
Functional test
Open the camera software or application and test whether all the functions of the camera module are normal, including previewing the picture, shooting, video recording, etc..

Fifth, Precautions
Safe operation
Before performing any maintenance operations, please ensure that the computer is turned off and the power is disconnected to avoid the risk of electric shock.
When handling electronic devices, please take appropriate electrostatic protection measures to avoid damaging sensitive components.
Warranty terms:
