DJI O4 Pro Camera Not Working (Black Screen in Goggles)
If you experience a black screen in your goggles when using the DJI O4 Pro camera system, it's typically due to a physical issue like a pinched or damaged coaxial cable connecting the camera.

Important Clarification:
If you purchased the DJI O4 Pro camera separately or installed it yourself onto a drone frame, any physical damage like a pinched cable is considered user-related damage and not covered by warranty. In these cases, please inspect and replace the damaged component yourself or consider purchasing a replacement part. However, if you believe there is a defect unrelated to installation or usage, please contact DJI directly for further support. If you encounter difficulties, feel free to reach out to us at Unmanned Tech Shop, and we'll assist you with the process.
Steps to Troubleshoot
Inspect Your Coaxial Cable:
- Carefully inspect the coaxial cable connecting your DJI O4 Pro camera.
- See the example image below showing what pinched cables typically look like:

- Clearly document the damage with photos or a video.
- Contact the drone manufacturer directly (Flywoo, GepRC, etc.) and provide your visual evidence.
- The manufacturer should authorize a replacement or repair under warranty.
- If you are within the UMT warranty period we can also help directly, and we will handle shipping for you (so you only need to return to the UMT warehouse, and we will ship out any replacements, or issue a refund according to our return policy.
If No Visible Damage:
