    I respectfully request any assistance available in isolating my problem before I get on the phone with my cable company tech support.

    Problem: Sometime around 8 August, I seem to have lost the ability to tune any cable channels on one of my two TivoHDs. The other one is behaving completely normally. On reboot, the tivo shows the 'acquiring channel list' screen for a while before timing out and going to a black screen on any cable channel with the error banner "The channel is experiencing network difficulties. Contact your cable provider...". This is the state on analog as well as digital channels.

    Looking through cable card screens, it looks like it has lost pairing. The pairing screen is headed by "In order to start cable service for this device, please contact your cable provider". I have requested a STB refresh via my cable company's (Charter) website, and also a pairing hit from a live CSR last night, with no change.

    I'd really like to know as much as I can about what is going on before I call back. Thank you all for any guidance you can provide:

    Data I can find that could conceivably be relevant, taken after a fresh boot

    Based on some hints on another forum, I tried power cycling the TA, and that helped. I no longer get the "network difficulties" banner, and many channels tune, but some channels can not get a signal ("searching for signal on: Cable in"). Perhaps TA commands are not getting back to head-end? Is there any way for me to troubleshoot/debug/isolate the problem?

    You had missing channel problems and didn't even mention you were using a TA in your first post?

    I have to power cycle my TA on average once or twice a month when channels go missing.

    The stuff you reproduce in your initial post shows modulation type as analog, which should not be happening with any channel for which a cable card is needed, 'cause all that stuff is digital modulation.

    Are there (still) any analog channels on your cable provider?
