What can I do if the audio is intermittent when playing the video?

If the audio is intermittent when playing the video, please follow the below methods to do the troubleshooting:

1. Make sure that there is one video input source inserted in the TV.
2. Unplug all other electric appliances from the wall socket except the TV.
3. Change another video to play on the TV.
4. Change another cable to connect the device to the TV. If you plug the device into the TV via the HDMI cable, please change another HDMI cable if you have a spare one.
5. Try to restore the TV to the factory default settings.
Press the Settings button on the TV remote, then select Settings --> System --> About --> Reset --> Factory Reset:
