Lost All Channels - Reboot Brought Them Back
I've been having periodic channel loss, but it was rare and usually only a single channel. Changing up or down then back to the lost channel recovered it.
Today I turned on the TV and had nothing. No channel content at all. Checking diagnostics on the TA and CC had no results, like they were disconnected.
Rebooting the Roamio brought everything back, but I need to find out what's happening. Is there a shortlist of things to check to see what might be happening?
