Cablecards authorize and decrypt channels, but they are not tuners, so a bad card would not be responsible for the weak signal messages you are seeing. The most likely cause is a poor connection to Comcast's network, usually in or near your home. Troubleshoot by checking all coax connectors for corrosion and tightness, and by looking for damaged cable. Running the cable through a surge protector, a defective splitter, or too many splitters can cause signal problems as well. If there is an amplifier in the line make sure it's getting power.
Thanks for this, I have checked all my connections (plus nothing changed when this issue started). I have what consider to be a clean setup: no cable splitters, no amplifiers, not running through surge protectors, nothing like that.
But why would a poor connection cause just a handful of channels to behave like this, I would imagine that a poor connection would cause all channels to receive error messages

I've been using an HDHomeRun Prime with a Comcast CableCard for probably 3 years now with no issues. It goes through Windows Media Center on a Windows 7 computer. Just the other day, with no changes on my end, a number of the channels cannot be used anymore and I get a "channel has a weak signal" error message. So far it's <10 channels, but they are some common ones (like PBS and ABC).
I tried rebooting my HDHomeRun, rebooted my computer, tried troubleshooting with Comcast on the phone... nothing has worked.
I'm wondering if my CableCard is showing it's age and maybe I need to swap for a new one?
On the "my.hdhomerun.com" page it shows I have a strong signal and good quality, card authentication and validation were successful as well. I'm on the latest firmware as well
Anyone have any experience like this that could offer a solution?
