Existing Cablecard stopped working
I know that Comcast no longer issues new cablecards.
I do have an existing cablecard though (which I have had for many years), but it recently stopping working. I am now receiving “V58 channel not authorized” messages on every channel. This seems like my existing card was removed from your system.
I would like to work with someone in your tech support area to add my card ID back into your database. This is an existing cablecard and not a new one so according to your press release it should still be supported. I currently have two cablecards on my account and am having issues with only one.
Thanks for your help!

If the card is a Scientific-Atlanta/Cisco/Technicolor PowerKEY card, it may have died due to a date-related internal flaw. See https://www.lightreading.com/cable-technology/time-warp-could-cause-millions-of-old-powerkey-set-tops-to-go-on-the-blink. I haven't been able to find a list of which cards are affected, but the PKM800 series and earlier seem to be in trouble.
What are the model numbers of the two cards? It's printed on the back of the card, and can also be found on the "CableCARD Diag" screen under "H/W Model".
I have a Tivo Edge using a Technicolor Multi-Stream PowerKEY Model PKM908 card (printed dated 04/01/20) and so far it's still working. FWIW the card's firmware (from the "CableCARD Diag Screen") "OS Ver" is "PKEY2.0.1_F.p.1101, Build Time: Nov 2 2022".
Before declaring a CableCard problem it's worth checking the Tivo's signal stats. See https://tivoidp.tivo.com/tivoCommunitySupport/s/article/Troubleshooting-Digital-TV-Signals. Under "Signal Quality" ignore the "Maximum SNR" spec. The higher the SNR, the better.

Interesting. The card that failed appears to be running the same firmware as the card in my Edge that's still working. Don't know what to make of that. A pity that Comcast/Xfinity has provided us with so little information about this situation.
I do not, nor would I ever! I'm just a fellow customer trying (in vain, I fear) to help others and to get the company to do better.

I have the same issue which started the afternoon of December 5. I am waiting for Comcast advanced tech engineer to call to further troubleshoot. My host TiVo and Cablecard are paired but no signal. I am now receiving V53 message on all channels. Earlier the message was V58. Now screen on all channels say “Problem with the signal on this channel. Trying again(V53).”
