Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, bear with us; re-confirm and post back with the complete model number of the "...Comcast cable box..." Additionally, please describe how the cable box is connected to the TV using what kind of cable(s).

Customer: replied 1 month ago.
Motorola cable box with coaxial cable
Expert:  Louie replied 1 month ago.

Appreciate the additional information.

That a "...Motorola cable box with coaxial cable... is connected to the Vizio E40-D0, then the Vizio would have to be set to TV mode / Ch 3 (or 4).

Are you able to go to Ch 3?

...or at least go to Settings Menu?

what/where is the control to set the tv channel?
Expert:  Louie replied 1 month ago.

If already programmed, then pressing the + CH - buttons on the basic remote should cycle through the available channels including 3 and 4.

Customer: replied 1 month ago.
basic remote doesn't show any specific channels.
Expert:  Louie replied 1 month ago.

Then the Vizio would have to be paired with a smartphone or table that would serve as a full remote.

Alternatively but depending on the Motorola's model/features, the cable box may be connected using yellow + red & white RCA-to-RCA cables instead of coaxial cable.
