What type of cables /connection do you have between the cable box (or satellite) and tv ?Is it HDMI or color coded component cables ?
If you have color coded cables then pull the plugs out and back in securely one at a time at both ends and see if that clears this up .
If it does then please take the time to rate my answer positively (use the stars to rate) if that answers your question as it is the only way i get paid for helping you , otherwise do not rate at all , just let me know and we`ll see what can be done.Note that you can reach me here at any time after rating if you have questions.
As I said above , I have no control over the phone (or other) offers , they are sent by the website ,not by me so ignore them
If you are connected to an antenna and the tv is processing its own signal then something definitely off with the main board adjusts or the main board itself .
Start with a full reset ;
Press and hold 10+ secs the EXIT button on the TV's remote until you see " Resets all settings to the default values "
If that doesn`t do it then the main board is suspect but if you are sure this happened with a remote control mishap then this should take care of it
