User Manual TCL LE48FHDF3300Z 48" Class 1080p FHD LED TV

If you have both analog and digital channels , the TV is looking for all available channels in the Channel List . If you do have digital channels , the TV is also searching for scrambled channels , non - scrambled channels , and each sub - channel of that digital channel .

Some channels enabled by the cable company don't carry programming , such as video ondemand .
When channels are unavailable , your TV screen is blank or appears like snow . You probably want to remove these channels from your Channel List . Remove these in the Channel Skip Menu .

Most digital video is sent in a 16/9 format which fills your screen , but is sometimes sent in 4/3 which does not fill your screen . It depends on how the station or device connected to your TV is formatting the video . If there are bars on the screen , press the ZOOM - / + button to try a different format that may eliminate the bars . Some bars can't be removed because of the way the format is sent by the broadcaster . The format changes as you press the ZOOM - / + button and the format type is displayed at the bottom of the screen .

Press the INFO button to display the Channel Banner . Look at the bottom right corner of the screen . The dot ( • ) is displayed for a digital channel . If there is no dot , it is an analog channel .

Besides using an off - air antenna as mentioned above , you can also use a set - top box to receive digital video . Contact your cable company or satellite provider to purchase digital programming and have them connect the box to ensure you are viewing channels the best way .
