    Well, the tuning adapter never gets recognized, it is at a constant state of initialization in the TiVo. This is both TiVos and both TAs. The TAs just blink constantly whether or not their USB is connected to the TiVo. And it is a constant blink, pauses. I’m thinking it’s a signal issue. Anyway to test those levels in another TiVo menu other than tuning adapter?

    Your guide is strictly a TIVO issue, you can't blame Spectrum for that.

    Well, things got worse today. Both TiVo’s lost all channels, not just SDV and every channel says either searching for a signal or the channel is not authorized. Happened while I was watching at Noon today and both TiVos had the issue without being touched. This is a new one. Called and Cox says everything is authorized and they aren’t sure what is wrong and are going to a send a truck Monday morning. I’ll probably have to FaceTime the tech while he checks the box outside. Weird thing is that the signal strength on the TiVo says 100% on one and 95% on another. They “re-paired” both Cablecars but still not authorized. The interesting thing is Now the Tuning Adapters are solid green! Sheesh! Anyway, it has to be the signal someone so hope they can fix it. Thank god for Netflix and Amazon Video.

    In an earlier post you said your TA’s were blinking “And it is a constant blink, pauses. “. Is it a constant blinking or is it so-many-blinks then pause, then repeat? 8-blinks-pause cycles mean the TA is not authorized and this is a totally different thing than pairing the CableCARD’s. If your CableCARD’s are “not authorized” (where did you see this?) then of course no channels will tune. Both types of authorization require good communications on two low frequencies below the cable channel frequencies, called Out-of-Band (OOB) signals and named FDC and RDC. It’s possible to have strong signals in the channel band (as evidenced by 95 or 100 in your TiVo signal strengths) but still have excessive attenuation somewhere along the cable path (either inside or outside your home) so that the OOB signals are too weak. If you are able to get the TiVo communicating with the TA, you can actually see signal levels for FDC and RDC. Otherwise it depends on the service tech being able to measure those specific frequencies. From what I’ve read on this forum, and my own experience, I don’t think they typically can do that.

    Now, even if the problem is NOT poor OOB signal levels, proper TA and CableCARD provisioning depends on settings made on your account at the cable head end. Errors of this type are by far the most common cause of problems like yours, based on thousands of war stories on this forum. Apparently very few cable co people really understand these issues which leads to some very frustrating situations.

    Until yesterday, the TAs were constantly blinking, no pauses. Then when I lost all channels yesterday, the TAs went Solid green, but the TiVos still do not recognize them nor receive any channels at all now. The cable folks are no help, saying that both cablecards are propery paired. They just had my power cycle everything twice before scheduling a truck roll tomorrow. We’ll see. The not authorized message appears on every channel when I try to watch.

    After you switch the splitters out to increase the signal,

    1) Disconnect the power and USB cable from the Tuning Adapter.
    2) Wait 60 seconds.
    3) Connect the power cable to the Tuning Adapter. Do not plug in the USB.
    4) Allow the Tuning Adapter to boot up completely (solid green light).
    5) After the light turns solid green, reconnect the USB cable between the TiVo and tuning adapter.
    6) After a few seconds you should get the notification from the TiVo that the tuning adapter has been connected.
    7) Wait about 5 more minutes, then check the settings below and see if any differ from what I have listed.

    This will increase the signal to each of your outputs, however I've tested this specific amplifier and it does not work with MoCA. I would suggest the CommScope one from my previous post which is designed to work with MoCA and would replace your 4-way splitter. Or, you can add one of these between your drop and your 4-way splitter - ANTRONIX FRA1-1510 CABLE TV BOOSTER AMP Forward/Return Amplifier HD COAXIAL COAX | eBay

    *** MORE INFO ***
    CoxInPHX in our Tivo Community wrote a post a few years ago that's very informative
    Cisco Tuning Adapter Status Troubleshooting

    I PM him and he gave me a little more info and wanted to share:

    I said:


    Near the bottom of your original post:

    Cisco Tuning Adapter Status Troubleshooting

    you have a list -

    The most important items in the Tuning Adapter Diagnostics should all read:

    What if ALL of item listed are not what they should be?
    What would that mean? I know my signal is very low. Also, this is my third Tuning Adapter.
    I just posted a week ago. Please check out my post and would love to get your expertise.
    Thank You.

    his response:

    Since you have replaced the Tuning Adapter twice, I would call and verify with Spectrum the TA Serial# and the RF MAC Address.
    Ask if the Ticket or Work Order for the TA swap is Closed. I've seen many times where the problem was simply an Open Ticket on the account.

    Your FDC of -18 or -19 is way too low, but may not be the issue.
    If you are using MoCA, disconnect that temporarily and use the TA RF pass-through to eliminate that splitter.

    I would bypass at least one of your splitters, (preferably the main drop) with a coax barrel connector, to see if that increases your signal enough for the DAVIC to Connect.

    It's also very possible some configuration change was made at the Cable Plant, which knocked all TAs off the Plant. This has happened to me before, It took many people complaining in the Cox Support Forums to get it fixed.

    He’s correct and was a great source of information while I was working to troubleshoot my Tuning Adapter issue.

    When you have a chance, test again with your 4-way splitter replaced by the 2-way. Post your signal levels and whether you're getting an RF IP Address a few minutes after the tuning adapter boots up. All of the other statuses (DAVIC, Status, Authorization, etc) will hinge on the Tuning Adapter getting that address.

    I would add one last step after all that and it worked for me yesterday. I rebooted the Bolt+ and voila. I've had my TA on a timer for a weekly reboot. Lately half the time it is messed up after the reboot- no SDV channels. Sometimes another reboot does it, but not always. I had gone years with nary a problem. I don't know if the headend software was changed or what. I have noticed that the TA reboot seems to be taking a lot more time than I remember.

    I've tried that so many times my fingers are stumps. Hee-hee. I'm pretty confident this is a result of Spectrum changes or updating something at the "cable plant". Or, maybe my drop line got damaged. Any changes, I'll always update. Right now, TA not really working (just a few channels) and waiting for a COVID-19 slow down before I order a truck roll.

    **** MAJOR UPDATE ****

    About a week ago I ordered an Antronix MRA4-8 Advanced Residential Amplifier:
    https://www.amazon.com/gp/product/B00CYMQVG4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1.


    I installed it today (4/26/20), with a 12ft RG6 coax cable to supply power from AC adapter to amplifier.
    I am now getting EVERY STATION I'm paying for - Spectrum Select package and the Digi Tier 1. All the suggestions and expert advice received for good/proper signal strength are all matched when checking tuning adapter signal levels via the Tivo Tuning Adapter Diagnostics pages.

    Hoping the good luck continues.

    Can't thank everyone enough for their input and expertise!!!!!
