If you are missing some of your expected TV channels it may be because:

1. Your Smart TV may not be updated with the latest firmware.
2. You may have subscribed to a package that doesn’t offer the channel.
3. Your broadcast provider may have changed the stations.

To attempt to fix this issue, you should:

1. Check whether your TV's firmware is up to date.
2. Confirm that you are subscribed to the correct package.
3. Contact your broadcast provider to ensure you are receiving the correct station information.
