Basic Troubleshooting

If you are experiencing issues with XFINITY TV Go videos, please make sure your device meets all minimum requirements. See XFINITY TV Go Online Overview for more information.

If your device meets all the minimum requirements and videos still are not working, try one of these tips:

  • If the video doesn't begin playing: Restart the web browser, select the video and click on the arrow to play.
  • If you can see the video but can't hear sound: Make sure the speakers or headphones are properly connected, turned on and not muted.
  • If the video is choppy or stalling: Streaming video or video playback (such as the videos on XFINITY TV Go) requires a large amount of processor (CPU) speed. To decrease the drain on the CPU, close other programs and background services that may be running at the same time as your web browser.

To check CPU usage for Windows users:
  1. Press Ctrl + Alt + Del.
  2. Click Task Manager.
  3. Click the Preferences tab.
To check CPU usage for Mac users, open the Activity Monitor Application:
  1. Open a new Finder window by clicking on the icon in the Dock.
  2. Navigate to the Applications section of your Mac hard drive.
  3. Open the Utilities folder within the Applications section.
  4. Double-click on the Activity Monitor icon to launch the utility program.
