Hi Karen, You can use the Spectrum app if that would be easier for you. Roku isn't necessary as it has Tizen built in which can stream most services. You can plug a coax cable directly into the TV, you'll just have to run a channel search afterwards. Simply connect the coax cable to the ANT IN port on the back of your TV.

Change the source on your TV to TV. There are a few ways to do this.

You can press the home button on your remote and then select the source labeled TV.

You can press Home again, navigate left to source, and then select TV.


Use the directional pad or arrow buttons on your remote to select Settings.

Select Broadcasting, and then select Auto Program.

Select Start to begin auto-programming, and then select either Both, Air, or Cable.

Select Air if you are using an Antenna only and you want the fastest results.

You can press Home, navigate left to source, and then select TV.

If you select Both, it will take longer to scan, but you may find more channels.

Your TV will begin to scan for channels. After it's done, select Close to finish.
I hope this helped, ^Scott
