You can perform a sound test to check for any abnormalities in the product.
If the sound is produced okay during the sound test, it may indicate a problem with the broadcast signal
rather than the product itself.
In this case, please contact your broadcast service provider for further assistance. (e.g., cable TV,
Skylife, IPTV) If the test sound has problems, you may need to contact LG Electronics service technician for
further troubleshooting support.
