New smart TV

[tedp]

I've installed a new Samsung smart TV in my motor home and I cannot get it to see the cable channels. I know the cable works because I can get my old "dumb" TV in the bedroom to see all the cable channels. I know the coax between the switch box and the smart TV is good as I can get over the air channels using the antenna. Could my switching box be bad? Any other help would be appreciated.

Got it! The switching hub cannot be powered on when using cable.
Thanks for all the help!

Not good enough wifi strength

I can stream off my phone. At home I can stream off my Netgear wifi module a 100+ feet away.

Ran coax from the campground cable direct to the back of the smart TV and it worked. So it means it's in my switch box I guess. Right?

Maybe. If running it direct from the pedestal worked, why do you need the switchbox at all? But if you want to keep the switchbox do you have the input and output the same? Maybe your switchbox isn't compatible or it's malfunctioning.

I thought maybe it was the switch box as well. It works for over the air channels so I switched around the leads from the antenna in and the cable coax in and that didn't work either.
I assumed I'd have to have the switch box so the bedroom TV would have cable as well.

That didn't work, thanks!

What inputs are shown on the setup screen?
What method are you trying to connect through? Actual cable from a provider?
Try switching TVs at the video box.

Have you changed the input on the TV to the COAX input and scanned the channels?

No coax in the input screen.

Verify the TV is set to cable and not antenna.

It is

Retired’s suggestion is great.
