I am trying to set up my comcast small black cable box with my new roku tv. i want it to be hardwired because when i stream through xfinity app it is very fuzzy. My cable box does not have hdmi option only coaxial. I have everything hooked up exactly how it was on my last tv which cable worked fine. When i go to "cable tv" it says no signal is it turned on. When i go to antenna tv to scan for channels and it only find 1 local channel. How do I connect cable via coaxial and get all my channels. Thanks
We have our Roku tv connected to our small black cable box but still receiving no signal and no channels found. We’re at a loss as to what to do. We hooked our cable into the Antenna /cable in port on our 40S325 model tv.
