Smart TV thinks Cable Box is a VCR

I managed to connect a Motorola cable box (Verizon FIOS) to a 43-inch TCL Roku TV, model no. 43S435, but to access it, you have to go to Antenna TV and it is listed on the Program Guide as "3 VCR". Why and what can I do to fix this?

It sounds like you connected it to the antenna input on the TV. (Which was a fairly common way to do it before HDTV.) If it has other outputs like HDMI, those would provide a much better picture.

Cable box is connected to the TV with a coaxial cable.

Forget the coax connection.  Does the cable box have any other kind of outputs - preferably HDMI?  Coax would give you the worst possible picture.

Re: Smart TV thinks Cable Box is a VCR

Why does the TV think it is an antenna connection and not a cable box? Is there a way to get the TV to recognize the cable box as a cable box through its current connection, a coaxial cable connected to where you would connect the antenna?

Does the cable box require you to have the TV on channel 3 or 4? If so, it's because it's sending a signal on that channel (frequency), just like an antenna would do. As far as the TV is concerned, that's what it is.

So much for it being a "smart" TV. Thanks.

A signal on channel 4 is a signal on channel 4, regardless if an RF modulator in a device generates it, or if an antenna picks it up over the air. 

Most TVs today aren't expecting 1980s technology connected to it.

Highlight the vcr input on the home screen and press the option * key, then rename it anything you want.

I got an HDMI cable today. Result: Way better picture than with coax cable.
