    Hello, I know there are some similar posts here abut this but they all appear to be quite old.

    I have a Roamio on Charter/Spectrum cable with a Motorola cablecard. I started losing channels almost 2 weeks ago so I called Spectrum and they redirected me to tivo who redirected me to Spectrum... so they dispatched a tech this week and everything looked good, but...

    So Spectrum started making changes to their system, updated my card firmware and that's when it broke. The technician said I needed a tuning adapter and installed it. The end result was the same as the start but now I have a tuning adapter and my more than half of my channels are missing. While there the tech received an email saying they have identified a problem and are working on it...

    The changes Spectrum made were to switch all of the tv signals to a smaller band of frequencies to make way for GB internet at home.

    I am just wondering if there is anyone else with this problem or has had this problem and might offer some insight on how long this could take.

    Lots of people have this problem. It is usually either the CableCARD is not authorizing some of your channels or your Tuning Adapter is not working. Sometimes it is a weak signal on the bad channels. (I had this last problem once because the splitter under the house got corroded away to almost nothing. In fact I have had all of these problems at one time or another.)

    Is the light on the front of your Tuning Adapter blinking constantly? If so, that is the problem. If not, here is TiVo's CableCARD troubleshooting link. If that's not the problem you should look at the signal strength for the missing channels in the Tuning Adapter diagnostics panel. If it's low but not zero you have a signal strength problem.

    I am also a Carter/Spectrum customer in the Ft. Worth, TX. area and experienced the exact same problem with missing channels on my Silver Package.
    My problems started on 9/30 when Spectrum upgraded their internet equipment in the area. It took many calls and tech appointments until my problem was finally fixed on 10/11 when Spectrum installed a Cisco STA 1520 tuning adapter to my TiVo Bolt Vox. My service is now back to normal.

    I had a similar problem recently. Tech guessed at a bunch of things before finally testing at the pole. Turned out the fix was having line techs come out and adjust levels. Some frequencies or something were being cut off.

    Make sure your signal strength is around 90% in your diagnostic screen. Just had a Bolt at 70% and it would not pick up some channels and some would pixolate and some would work OK. I found a loose coax connector on a splitter and the signal went to 90% and all channels started working.

    Thanks so much for the feedback.

    I live in Northern California. I got a call today saying they solved the problem but I still don't have my channels.

    I know about the issues regarding corrosion, as the tech found a lot of corrosion and very low signal strength in a lot of the frequency spectrum. They resolved those issues at the house, the tap and the pole, and claimed the problems were on "their" end at that time.

    The tuner adapter they installed was an mtr700, and the light flashes constantly but my Roamio seems to think it is working ok.

    Signal strength is not shown, just a hyphen.

    I will update if I hear anything else. Thanks so much again for the feedback, you have given me more to talk to the techs about.

    Flashing means it ISN'T working. So no surprise you still don't have your channels. Solid amber light means it's working. You need to call them back and confirm the TA is actually on your account AND enabled. It also may not be connected correctly, as MOCA can interfere. So if you're using MOCA, make sure you put a POE filter on the input. It's also best to split the incoming coax with one leg to the input of the TA and the other to the input of the Tivo. There shouldn't be any connection on the TA coax output. The only connection between the TA and Tivo should be the USB cable.

    About 3 weeks ago I lost most of my Spectrum channels. I decided to reinstall my tuning adapter and the missing channels returned. I may have had to call tech support to get the tuning adapter to stop flashing as it had been disconnected for over a year.

    The bottom line is that Spectrum (in at least) NW North Carolina convertred most channels to SDV.
