Somtimes the volume, channel, and other functions will not work. TV still has picture and sound, but cannot change the volume or channel or even turn off. Neither the cable remote or the original tv remote will respond. The manual buttons on the TV will not respond either. When unplugging the TV and plug back in is when the controls resume working. Is this a TV issue or a cable box issue?
Hi jtg77. Being that the TV does not respond when you use the TV remote and when you manually press the buttons on the TV, it sounds like you have a problem with your TV.
Please let us know if we can assist any further.
