To troubleshoot your Smart TV’s missing channels, please follow these steps:
Check your antenna or cable connection: Disconnect and reconnect the connection to your TV and see if the issue is resolved. Check if the channels are available in your service’s range: Some channels are not available in all service locations. Check with your service provider. Download new software: If your Smart TV is currently on outdated software, download the newest version. Factory data reset: If none of the other steps worked, it may be worth performing a factory data reset.
