Samsung CU7000 TV Displays "This Function Is Not Available" in Broadcast Settings

For the past three days, while using the built-in satellite receiver on my 58-inch Samsung CU7000 TV, the error message "This function is not available" appears on the screen whenever I try to open the broadcast settings, preventing me from updating the newly changed satellite frequencies. Because I encounter this warning whenever I try to navigate to the menu settings and access broadcast options, I cannot edit my channels or perform frequency updates.

I am experiencing significant frustration due to being unable to use my TV to its full potential. I demand that this issue be permanently resolved as soon as possible, that necessary software/settings support be provided, and that my device be brought to a state where I can update satellite frequencies without any issues.
