At a Glance
- If the TV volume is low even after you turned it up, please check the volume on the set-top box.
- If the volume is turned up and the audio is still low, you can run a sound test to determine whether the TV sound output is abnormal.
- If the voice in the sound test sounds normal, it may be a problem with the broadcasting signal, not the TV.
If it’s an issue with the broadcast signal, you can reset the set-top box to resolve it.
If the rest does not solve the issue, please contact your carrier. (e.g., cable TV, Skylife, IPTV)
