Follow the steps below to troubleshoot this issue.
IMPORTANT: If the camcorder is connected to the TV using an S-Video or a component cable, the red and white audio connection also must be used. S-Video and component cables only carry the video signal to the TV.
- Because each of these steps represents a possible solution to this issue, check the sound after completing each step.
- If model-specific information is required to complete any of the steps in this solution, refer to the operating instructions supplied with the product. Manuals are posted on your model support page.
- Ensure both ends of the cable you are using are connected securely to both the camcorder and TV.
- Ensure nothing is connected to the headphone jack on the camcorder or the headphone jack on the TV.
- Ensure the television volume is not muted.
- Try increasing the volume on the television.
- Check if there is an output setting in the camcorder menu that needs enabled.
- Connect the camcorder to different video input on the TV.
- If your camcorder uses a tape, try playing a different tape.
NOTE: If the tape was recorded with a different camcorder, the issue may be related to the compatibility of the recording made from the other camcorder. Attempt to playback a tape recorded with this camcorder to see if the issue remains.
- Try connecting the camcorder to another TV.
- Replace the connecting cable.
