A Time Warner cable box transmits both video and audio through cables to a television set for viewing. To fix a lip-sync problem -- when the audio is not matching up to the video -- you need to set commands that remove the problem from the cable box, TV and the cable connecting the two together. The procedures do not require any tools and will not harm the cable box in any way.
Step 1
Unplug the Time Warner cable box's power cord from the outlet. Let 10 minutes pass. Plug the cord back into the outlet. Press the "Power" button on the cable box's remote control to turn the cable box on.
