2. The cable box will begin restarting. Your box should resume playing in 5–20 minutes.

5. Check Cabling

Identifying what kind of cable connects the box you wish to be seeing on the screen (cable box, DVD player, etc.) of your TV is very important. This will help make absolutely sure that the correct input settings are being used and that there is not a loose or bad connection with the cables being used. The kinds of cables being used and where they are connected will be different in every home theater setup.

The most common types of cables you may encounter when looking at your Home Theater equipment:

• HDMI
  

• Component Video
  

• Composite Video
  

1. Start with the box you're attempting to get picture from, like your Cable box or DVD/Blu-ray player.
   

1. On the back of the box, check to see what kind of cables are connected and trace them to see what and where they are plugged into. While checking, make sure each cable is securely connected and pushed in firmly all the way.
   

1. In this example, the HDMI cable that comes from the cable box is connected to the HDMI2 input on the TV. This means the TV would need to be set to HDMI2 to see the picture from this cable box.
   

1. Check that all cables are securely connected and take note of the names of the ports that those cables are plugged into so those specific inputs can be tested.

6. Check Input Settings

Your Xfinity TV components may need to be using different "input" or "source" settings in order to be able to find sound or picture properly. This will be different in every home setup depending on the cables that are being used, and the different components that you have installed. These generalized steps will touch upon how you can check and adjust the input settings of your components to make sure they're correct.

Seeing a 'No Signal' image on your TV like the one above means your TV is likely looking for picture on the wrong Source or Input.

If you have a home theater system connected, make sure the unit is turned on and set to the correct input source.

To Check and Change Sources on Your TV

1. Locate the Input or Source button on your Xfinity TV remote.
   

1. 
   
2. If your Xfinity remote is not programmed to control your television, you may need to use your television's remote control to adjust input settings.
3. Aim the remote at the TV and press the Input or Source button to begin cycling through the available inputs on the screen until you reach the proper input.
   

1. Ensure you are tuned into a channel included with your Xfinity service.
