A week ago, I stopped receiving some of the channels that I pay for on Comcast. The local affiliates for NBC and CVS showed a status code of “S0a00.” The “fix” was to unplug the HD DVR box and plug it back in. Essentially this is rebooting the operating system. I’m technology-minded, makes sense. The same problem occurred yesterday. This time rebooting the system didn’t fix things. This lead me down the rabbit hole to explore a number of things regarding Comcast and my cable service.
- There is a secret diagnostics mode – There’s a secret diagnostics mode on the cable box. If you are watching television, press power and then ok/select three times fast. You’ll get a white screen with a number of options. The fourth option for me was the Inband Status. From there I could get the value for “SNR” (Signal to Noise Ratio). From the channels that weren’t comming in the reading was 27 dB. On the good ones it was 33. You want a range between 33 and 37.
The research about not being able to buy a cable box, lead me to do quite a bit of research… actually a lot of research. In the next couple of weeks, I will likely expand on this in greater detail. That’s if I have the “Moxi”.
