No sound or poor sound quality

If no audio signal is detected, the TV automatically switches the audio output off. This is not a malfunction.

• Make sure that the sound settings are correctly set.
• Make sure that all cables are properly connected.
• Make sure that the volume is not muted or set to zero.
• Make sure that the TV audio output is connected to the audio input on the Home Theatre System. Sound should be heard from the Home Theatre System speakers.
• Some devices may require you to manually enable the HDMI audio output. If HDMI audio is already enabled, but you still do not hear any audio, try changing the digital audio format of the device to PCM (Pulse Code Modulation). Refer to the documentation accompanying your device for instructions.
