Hi Hate this TV, We're sorry you are experiencing issues connection your antenna to the U7900FD TV. Please know you can connect your antenna via HDMI or AUX cable. Then please try the following troubleshooting steps to resolve the issue: 1. Confirm external device setup: Make sure the external device (such as a cable box, game console, or Blu-ray player) is securely connected and powered on. On your TV, go to: Home > left directional key > Connected Devices > Sources, and confirm the correct input is selected. 2. Reconnect and test cables: Remove and firmly reconnect all HDMI or AV cables between your TV and the external device. Try using a different cable if possible. 3. Power cycle your equipment: Unplug the power cords to your TV and the connected devices. Wait 30 seconds, then plug them back in and power on each device. 4. Run a Picture or Sound Test: These tests help determine if the issue lies with the TV or the connected device. Go to: Home > left directional key > Settings > Support > Device Care > Self Diagnosis > Picture Test or Sound Test. 5. Use HDMI Troubleshooting: Home > left directional key > Connected Devices > Connection Guide > Video Device > HDMI Troubleshooting. This tool checks HDMI connections and helps identify potential issues. 6. Check signal strength (for antenna users). If you're using an antenna, go to: Settings > Support > Device Care > Self Diagnosis > Broadcast Signal. Here you can view signal strength and adjust the antenna position if needed for better reception. 7. Run Auto Program (if not using a cable box). If your TV is connected directly to a wall cable outlet or antenna, try running Auto Program to scan for available channels: Settings > All Settings > Broadcasting > Auto Program 8. Check network status (for streaming sources): Settings > All Settings > Connection > Network > Network Status, and make sure your TV is properly connected to the internet if you're using streaming services or apps. If you still see the “No Signal” message after trying the above, please call Samsung Support at 1-800-SAMSUNG ((8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun)).
