Hey i have a sony dav tz715 i have a prob with the sound
It seems like you're experiencing an issue with the sound speakers on your Sony DAV-TZ715 system when using the USB function with RFD multi mode. However, the problem resolves itself when you switch to other functions like TV. There could be a few potential causes for this issue:
1. Interference: The USB function may be more susceptible to interference, which is causing the noisy sound on the SUR L and R speakers. This interference could be originating from the USB source itself or other nearby electronic devices.
2. Compatibility: There could be a compatibility issue between the USB source and the RFD multi mode on your Sony system. It's possible that the USB source's audio format or settings are not fully supported by the RFD multi mode, resulting in the noise issue.
3. Firmware or software issue: There might be a firmware or software problem with your Sony DAV-TZ715 system. It's worth checking if there are any firmware updates available for your system that could potentially resolve the issue. You can visit the Sony support website or contact their customer support for assistance with this.
To troubleshoot the problem, you can try the following steps:
1. Test with a different USB source: Connect a different USB device or try playing different audio files from the same USB source to see if the issue persists. This will help determine if the problem is specific to the USB source or if it's a more general issue.
2. Check audio settings: Explore the audio settings on both the USB source and the Sony system. Make sure the audio format and settings are compatible with the RFD multi mode. You can refer to the user manual of your Sony DAV-TZ715 system for instructions on adjusting the audio settings.
3. Isolate interference: Move the USB source away from other electronic devices and potential sources of interference, such as Wi-Fi routers, cordless phones, or microwave ovens. This might help reduce any external interference that could be affecting the sound quality.
4. Perform a factory reset: If none of the above steps resolve the issue, you can try performing a factory reset on your Sony system. This will reset all settings to their default values. Refer to the user manual for instructions on how to perform a factory reset.
If the problem still persists after attempting these troubleshooting steps, it's recommended to reach out to Sony customer support for further assistance. They will have access to specific knowledge about your Sony DAV-TZ715 model and can provide more specialized guidance in resolving the issue.
