Try Unplugging your TV and cable box for a few minutes, then check the cables from the Cable box to the TV, plug in both devices and then turn on your TV and make sure you select the correct Sorce HDMI 1 or 2 ,If don't see a picture, select the home screen menu on your TV and then select the broadcasting menu and select service provider information and settings and follow the instructions to add your cable box, if this doesn't work select the device care menu and run the diagnostic tools to check your TV for any issues

I have done all those things and still won’t connect to cable box. Broadcasting menu doesn’t show Spectrum as something to connect

Try selecting my service provider isn't listed this will bring up an option to select Spectrum. Make sure you are using HDMI 1

So you said cable box, so I'm assuming it connects via HDMI. Correct .. and you correcting have the HDMI cord in the proper port on the TV and even on the back of the cable box ..? Some cable boxes have a HDMI in and out .. make sure it's on the HDMI out on the box
