No cable WiFi strong

Message pop up says no cable connected. HDMI1.  "Press SOURCE on your remote to select connected source device. I pressed source and tried selecting HDMI1 with no luck...then tried HDMI2 still no luck.  I've checked connection, run a reset on system and individual box. WiFi is strong and working .Can't connect to guide or tv.  Is my source device HDMI 1 or 2?  During this unprecedented time with covid-19 it's a difficult time.

You have to look at your TV to see what HDMI port your cable is connected to.  Then follow that cable to see where the other end is connected.  You might reconnect both ends to ensure good connections.  You might also change HDMI cables if you have an extra one.  If your TV still says no signal on the connected HDMI port, then the port on the TV Box/Modem isn't providing a signal.

Did this ever work or is this a new install/new TV?

Is your cable box powered on? If you’re using hdmi (nobody is going to be able to tell you what port you’re using, you have to physically look) unplug the hdmi and plug it in at both the tv and cable box.
