What can I do if the audio is abnormal when using the Multiple Inputs/Outputs port?
If the audio is abnormal when using the Multiple Inputs/Outputs port, please follow the below methods to do the troubleshooting:
About this issue, we need to do cross-checking to confirm the root cause.
- Plug the USB drive into another USB port on the TV.
- Change another USB drive and insert it into the USB port, and then check the video quality on the TV.
- Unplug the video source devices from the HDMI ports or the AV port or the satellite input ports, so we could confirm whether the interference causes the issue.
- Try to restore the TV back to the factory settings: press the Home
button on the TV remote. Then select Settings-->Device Preferences-->Factory Reset.
- If the TV has internet access, please check if there is a new version of software updated online or not.
Press the Home
button on the TV remote, and select Settings-->Device Preferences-->Aboutà-->System update-->Network Update:
If the issue cannot be resolved, please feel free to call the TCL hotline for further help.
