Basic connection.

Basic connection.

Cannot find signal channel. Cable box, modem and TV all seem to be working, but tv showing no signal. It’s trying to connect on channel 40. Have done both system refresh and cable box restart. Shoul the TV be set to a different channel for the audio feed?

Re: Basic connection.

How’s the box connected? Where do you see channel 40?

The TV first shows HDMI 3 cable. After some time, that goes away and it shows Channel 40. The that goes away and it shows No Signal.
