Cablecard Service

I've been successfully using a cablecard with an InfiniTV in suburban Chicago since 2012. On 2/15/2026 I noticed HD channels no longer worked but standard definition (SD) channels were fine. On 2/16/2026 SD no longer worked either. On 2/17/2026 I can now see some SD channels but they are very pixelated as if the codec was changed. I'm aware of support ending for cablecards but that troubleshooting is still done. Was something done this past weekend that would cause these changes?

@user_j7f2m3 Thanks for reaching out for support. Cable cards are being phased out. In all honestly this is how it starts with the HD channels not working and then SD follows. We can try some troubleshooting steps with you. I do recommend considering adding a rental cable box from us or using a different customer own device that's supported with our current network. I have a link with those devices here https://www.xfinity.com/support/articles/xfinity-stream-app-faqs

Do you have more than one cable card devices with this error?

Just one. It is now later in the morning of 2/17/2026 and everything is back to working fine. Maybe they were doing some testing. I also have a DTA box for a legacy TV which was fine all along.

Over the last couple of days TV through cablecard has alternated between not working, partially working, and fully working. So I'm now unsure if the problem is cablecard-related. Should I work through you for the problem or call support?
