Sound with banner but no picture - Time Warner TV

#1
This question is about "Sound with banner but no picture", with Time Warner Cable TV and apps. Somehow a button was hit on the cable remote and we have sound with the cable channel banner but no picture. We checked the TV with a USB and a photo appears so it's not the set which is new. Unplugged everything to no avail. Any ideas as to what might cause this?


This topic covered Sound with banner but no picture, and TWC cable tv service.
