Why is there no sound on my LG TV but picture is fine?
If your LG TV displays no sound but shows images, first, press the VOL + or - button to adjust the volume. Check if the sound is muted by pressing the MUTE button. Try switching to other channels to rule out a broadcast issue. Ensure the audio cables are properly connected and verify that the TV Speaker feature is enabled in the menu.
