This article explains how to access Share on your TV.
Accessing Share by Changing the TV Input
You can use the Input or Source button on your TV remote or the side of your TV to change the input and access Share. When you press the Input button, the TV will show you a list of different input choices. Your Share player is usually connected through one of the HDMI inputs. Use the remote's arrows to select the right input.
When you want to switch back to watching TV, use the input button again to switch to the appropriate input for your TV source.
Accessing Share in PassThrough Mode
If your Share player is set up in PassThrough Mode, it will allow you to switch between watching TV and using Share just by pressing the TV and LS buttons on the remote.
Press the button at any time while the TV is turned on to access Share.
To return to watching TV, you can either press the button, or use the arrows on the remote to navigate to Watch TV, then press OK.
