It will not be your TV. Many times when you get an error message, The first thing you should do is reboot your cable box. It resets the system and gets rid of glitches just like rebooting your computer. If that doesn't work, then call your provider and they will probably be able to do fix it remotely while they have you on the phone. They will simply send a signal thru your cable and will probably ask you what you see while they are sending that signal.
Not necessarily true. After contacting my ISP, Netflix and Samsung, several times each, it was my TV. Samsung solved it remotely.
