I don't have a wire to connect my cable box to an HDMI input however I've connected the cable box through the Antenna/Cable input which is how I connected it on my old TV.

Cable boxes connected that way must be accessed via the Antenna/Live TV option on the Roku TV.  The cable box likely has its output on either channel 3 or 4, so you have to set the TV tuner to display the proper channel.

    And to add... if that cable box has an HDMI output do yourself a favor and get an HDMI cable to connect it to your TV.

      I currently have my cable box connected via coaxial cable.  I can't get HD channels.  So I needed a new box with an HDMI port.  Technician came out and could NOT get TV to connect to box.  He stated it is TV port, yet my blu-ray player works on the HDMI ports.  He tried several boxes and 2 separate HDMI cables. All we got was a green screen, no sound.

        Did you try removing and adding a new HDMI Input from the Roku Settings?

        Settings..TV Inputs (Select a HDMI input) and then Setup Input.

        After you hook up HDMI cable, try doing a System Restart (Settings..System Settings..Power..Restart)

      monty3, instead of questioning the knowledge of other people why don't you tell us what you're trying to do?  Do you have a Roku TV and not a Roku player connected to a TV?  If so, did you add channels 3 and 4 when you scanned for antenna channels?  Your attitude is quite off-putting.

        I am having the same issue.  My cable box worked great for 2 years and then the Roku Tv stopped recognizing the cable box.  I swapped the cable box for a new one and it still says no signal.  I also put on a brand new hdmi cable and still the same.  I have reset all the settings back to the factory settings and still I get the red screen saying no signal.  Help please.
