Hi,
If your U8000H TV isn’t receiving all available channels, first check that your coaxial cable is securely connected. Then, try running Auto Program by going to: Home > left directional key > Settings > All Settings > General & Privacy > Broadcasting > Auto Program
If the issue persists, a factory reset may help: Home > left directional key > Settings > All Settings > General & Privacy > Factory Data Reset (this will restore all settings on your TV)
Please also note:
• Broadcasting settings are only accessible when your source is set to TV.
• These settings are not available when watching TV via a cable or satellite box.
If you continue to experience issues, please don’t hesitate to contact Samsung Customer Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat agents and additional resources are also available through the ‘Support’ link on our Samsung website.
