Hello and thank you for choosing Just Answer, I will be more than glad to assist you trouble shoot the problem. What do you have connected to the TV as a source (antenna, cable, satellite, DVD player etc.) and how is it connected (Coax, HDMI, RCA cables, component, etc.)? A lot of times the CC may not be coming from the TV but rather from the source. At the same time if you are using cable or satellite and you are turning the CC off using the cable remote than you most likely have the CC turned on from the TV.
