Samsung UN65MU8000FXZA Sound Troubleshooting Guide

Testing the Sound

First perform a sound test to confirm any sound problem. Follow this procedure to

• Select Home > Settings > Support > Self Diagnosis > Start Sound Test

If the TV plays the Start Sound Test melody without distortion, there may be a problem with an external device or the broadcast signal's strength.

There is no sound or the sound is too low at maximum volume

• Check the volume control of the device (cable or satellite box, DVD, Blu-ray, etc.) connected to your TV.

The picture is good but there is no sound.

• Set Settings > Sound > Sound Output to TV Speaker. If you are using an external device, check the device’s audio output option. (For example, you may need to change your cable box’s audio option to HDMI if the box connected to your TV is using an HDMI cable.)
• To listen to computer sound, connect an external speaker to the computer’s audio output connector.
• If your TV has a headphone jack, make sure there is nothing plugged into it.
• Reboot the connected device by disconnecting and then reconnecting the device’s power cable.

No sound is heard.

• Check whether the Digital Output Audio Format is set to Dolby Digital+ in Settings > Sound >  Expert Settings > Digital Output Audio Format. If you are using a receiver that does not support Dolby Digital Plus, you will hear no sound when you select Dolby Digital+. 

The speakers are making an odd sound

• Make sure that the audio cable is connected to the correct audio output connector on the external device.
• For antenna or cable connections, check the signal information. A low signal level may cause sound distortions.
• Run Start Sound Test ( Settings > Support > Self Diagnosis > Start Sound Test)
