No sound on TV

No sound on TV

Today we turned on the TV and had great picture - but no sound.  Tried mute & unmute, volume +/- , changed channels, etc - nothing worked.  


So, I unplugged the Xfinity box, it rebooted and we had sound.


Now, 6 hours later, no sound again and this time reboot did not work.


Please help

Your cable-box may be failing. I would exchange the remote and box at your nearest service center, or call Comcast for help on the current box.

I will recommend trying this steps first before swapping the box



after trying that steps let us know if you are still having issues

Re: No sound on TV

I lost sound on only channel 820, Fox News.  Pressing shortcut key D on my XR2 remote control restored the sound.  No matter what channel I am tuned to, pressing key D mutes channel 820.  So, if I accidentally bump key D, I may not immediatelly realize that channel 820 has been muted.
