    Your loss of OOB signal is probably your problem. It’s the 74.250 mHz control signal that delivers the channel tables and authorizations for the TA (and the cableCARD uses the same thing for its OOB lock so you can check that on your cableCARD tab in the Ceton web interface.

    Just looking at this, I’d call TW and have them come out and check signal strength. That your most likely cause of the OOB lock error. It might be on the edge and drops off from time to time. Remember that no cable system has either a flat response from dc to 1000 mHz and that the signal level will vary over time. You can check signal level on a few channels in the web interface by clicking on each tuner when it’s in use. You should try and get a signal level +/- 7 dBmV although TW thinks that +/- 10dBmV is good enough. But considering your issue they might just put an amp in the line. Let them do it for two reasons: A) they don’t charge for it and B) they’ll spec it for the right levels down and up. (The amps aren’t adjustable but they come in several versions).

    With any luck, if you’ve had issue with pixelation on some channels, that should clear up as well.

    OOB FREQ: 75.250 MHz
    CARRIER LOCK: YES
    SNR 24 dB GOOD Really not as good as your channel below. Should be 30+
    DATA: YES
    HUNT MODE: NONE

    INBAND FREQ: 561.000 MHz QAM256
    CARRIER LOCK: YES
    SNR 36 dB GOOD  Yes good
