Lost all channels (mix of no signal and not authorized)
Sometime early yesterday morning, we've lost all channels on our Tivo Roamio Basic. We have limited basic cable through Comcast and use a CableCARD, which has all been working great since January. The TiVo is still running 20.3.8.
The strange thing is that the channels now report a mix of causes for not working. Some report a signal problem (V53) and some report "not authorized". It seems that more channels report "not authorized" than V53.
I rebooted the TiVo, unplugged and replugged the coax cable, and removed and reinserted the CableCARD, all of which had no effect on the symptoms.
I guess my next plan is to call Comcast and see if they can help. I can't remember ever seeing this kind of issue before in many years of enjoying TiVo.
Thanks for any suggestions.
