New smart TV

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.
  • I found on my Smart TV that the power supply had to be off when hooked to campground cable for it to work.

    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.

    That didn't work, thanks!

    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.

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