Why is there no sound coming from my LG SPH4B-W Speaker System?
If your LG Speaker System has no sound, first, ensure the correct input source is selected. If the sound is still absent, check if the mute function is activated and deactivate it by pressing the Mute button or adjusting the volume. If you are using an external device, make sure the volume level on that device is also properly adjusted.
