You can perform a picture test to check for any abnormalities in the product.
If the image on the test screen appears okay, 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 picture test screen does not display correctly,
you may need to contact LG Electronics service technician for further troubleshooting support.
