Advertisements I have a Roamio pro and a Series 3 both with cablecards and tuning adapters from Optimum On long island. Both tuning adapters were installed within the past year and both have the same software version and both worked ok. But on 12/27/20, both of the tuning adapters stopped working to unblock the SDV channels. I rebooted both, but only the Series 3 tuning adapter started to work OK with unlocking the SDV channels. When I try to tune a SDV channel on the Roamio, it says "This channel is temporarily unavailable...". Here is the reason for the question in the title of this thread... When I originally obtained the first TA for the roamio (about a year ago), optimum mysteriously added a "Cable Box" to my bill for $11/mo even though the tuning adapter was free. Six months later and a dozen phone calls I was able to get the phantom cable box removed from my account. Six months later I got another tuning adapter for the Series 3 Tivo and the same thing happened and I had to spend time to get the second phantom cable box removed. Now, when I look at my current cable bill, it shows the two cablecards that I am being charged for, but it only shows that I have one tuning adapter (no charge). So, I'm thinking that due to all the changes made to my account to remove the two phantom cable boxes, I'm thinking that the first tuning adapter (for the Roamio) was maybe accidently removed from my account, so only the one for the series 3 is registered on my cable account and I'm hoping that the reason why the first tuning adapter is NOT working is because it was removed from my account sometime during all those account changes to my account and the first tuning adapter kept working past those changes until some system cleanup was done on 12/27 and then it stopped working because the system de-authorized the first tuning adapter because it was not on my account. So, does anyone know if tuning adapters need to be "authorized" or "registered" on an account for them to work, and if so, is it a simple process of just getting optimum to register the STB s/n of the (first) non-working TA to get it working?
