7. Troubleshooting

This section addresses common issues you might encounter with your Blackmagic Design Web Presenter 4K.

7.1 No Power / Unit Not Turning On

• Check Power Cable: Ensure the AC power cable is securely connected to the unit and a working power outlet.
• Alternative Power: If using the 12V DC input, verify the power supply is correctly connected and providing the specified voltage.
• Power Outlet: Test the power outlet with another device to confirm it is functional.

7.2 No Video Input Detected

• SDI Cable: Ensure the SDI cable is securely connected to the "SDI In" port on the Web Presenter 4K and to your video source.
• Video Source: Verify that your video source is powered on and outputting a signal. Check its settings for correct output format.
• SDI Compatibility: Confirm that your video source's SDI output is compatible with the Web Presenter 4K's input specifications (e.g., 12G-SDI).

7.3 Streaming Issues (Buffering, Disconnections)

• Network Connection: Ensure the Ethernet cable is firmly connected and your network is stable. A wired connection is highly recommended for streaming.
