Facing TV Problems? Ask a TV Technician.
Hello, Are you using a cable box with the TV please? Or is it direct coaxial connection from the wall to the back of the TV?
Also, what remote are you using (Vizio or cable provided remote)?
Thank you for the reply. If using a cable box, the CC function is generated by the box itself- not the TV. Have you tried rebooting the box by disconnecting it from power for 10 seconds then plugging it back in to reboot? If not can you try that please?
Do you need further assistance with this?
