  • Cable sound cutting out: if your issue with your Comcast cable is that you cannot hear the sounds coming out, because of maybe a Network outage – from Comcast’s end – your cable settings – your MTS/SAP settings may be jumbled up – or maybe you have not adjusted your default audio track, the TV box or adapter connectivity problems, or your Cable TV connection with your TV, or just the audio input. For any of these problems, below are the solutions.

Your TV box or adapter connection problems – ensure that your TV is not on mute 

Your connection with the TV – double check your connection cables using a multimeter and if they have problems replace them.

  • Broadcast signal quality is poor: if your cable Tv is cutting out but only for some channels, while others work fine – this is especially a serious problem if you’re the channels cutting out are your favorites – it most likely is from the broadcast signal from Comcast and has nothing to do with either your internet connection or your cable box, so you would need to call Comcast’s support so they can identify the problem from their end and rectify it.
  • Multiple connections to one device: when several people are connected to your device and are all on high internet usage like streaming or downloading, this could affect your internet and lead it to cut out, but you would need to confirm this first, try disconnecting majority of devices and leave only a few and see if the disruption stops, if it does stop, then you will need to increase or upgrade your internet plan so it can accommodate more devices to your internet connection.
  • Poor/Bad cables/ cable connection: you always need to confirm your cable connection the moment you start experiencing cut-outs, you are checking to see if they are old and corroded or frayed or rusty or if they are loose, loose cables can lead to partial connections which affect your cable TV or even your internet, also be sure that none of the cables are damaged and bent or knotted, any of these could affect the cables and in turn give you problems.
  • Xfinity box is no longer responding: sometimes the problem is with your box and a simple factory reset may do the trick, to know if the box is not working, check for the Comcast box power light and see if it is glowing, if it is not glowing try pulling the plug out and in again, if the light still does not come on, then reset the digital adapter. A detailed explanation of resetting and restarting the box is given below.

 Resetting the Comcast box

Resetting is quite different from restarting, which involves restoring the box to its default setting so all preferences and data you saved initially or over time would be deleted.

  1. Open the app and go to the overview menu 
  2. Click on the TV option 
  3. Select the device you want to troubleshoot and click troubleshoot 
  4. Then lastly tap on continue and select system refresh to reset the selected cable box.

You can also use the restore option to perform a factory reset if you do not want to use the app. To use the restore option just simply follow the steps below.

  1. Press and hold the power switch on your box to switch it on and confirm it is on.
  2. Open the user settings by pressing both the power and menu buttons at the same time on your remote.
  3. Locate the restore options in the setting which is usually the last thing 
  4. Click on the restore option and follow the prompts to start the process.
