Any idea what could be causing that sort of problem? The first Comcast rep I spoke with didn't have a clue--he told me I had upgraded to "Limited Basic" back in September, and wanted me to unplug my HDMI cable as part of his problem solving. The second one knew more, but still couldn't help me.
If the hit didn't fix it, usually this has something to do with DRM and the playback of protected channels. If you are in a moto area, sometimes these hits reset the data id which will then need to be verified that it is proper in the account. Usually the page you get this information does not refresh automatically so be sure to refresh the page and see if the id changed.
what does the status summary say?
Somewhere it should say :
Card Authentication success
Card OOB Lock success
Card Activation success
Whats the tuner status when tuned to a problem channel?
I'd be looking at CCI and cgms such as:
CCI Protection unrestricted
CGMS Protection n/a
Since its intermittent, what are the signal levels like and does your system use SDV and require a tuning adapter? Usually comcast doesn't use sdv so it's unlikely you need a tuning adapter. Occasionally I've seen bad card maps get pushed out so if you have a device that can tune the channel, check and see if it is tuning the same physical channel such as 101.5, with a "." or "-" (or frequency/program number) not the virtual channel of 192 without any program number.
I had one location where many TA requests were being ignored and if the channel happened to be "on" would tune fine but if it wasn't on, it would not serve the request.
Is the station in clear qam? There are lots of things that can "confuse" cable card tuners/WMC when they are tuning clear qam stations and the subscription status or cci isn't present. Occasionally I see similar errors when playready and wmc isn't properly set up for a cablecard tuner, especially when all one's subscribed channels are clear and/or copy freely and then all of a sudden there is some form of drm on the channel that isn't expected.
As you noted your problem before was a filter, since you say its intermittent I doubt the filter is back but on occasion I've seen channels moved without regard to the filters that are in place and/or audit on lines put filters back mistakenly, For me it happened when they re-labeled the lines in a condo complex and they put the unit number of my neighbor on my line... at the time this only affected tuning the analog versions of channels so my boxes didn't care, but a later change in frequencies then blocked digital channels I subscribed to, I had to take off two days of work since they "required" my presence and didn't show the first day (funny how they didn't require my presence to mess it up) but the guy came and fixed it even before knocking on my door and brought me down and showed me the old tag on the line plainly stating my unit number while the new tag had the wrong number and the line next to it had the same number so when the auditors came they put the filter on my line by mistake.
Recently I read a post over at SD's forum where a problem was that his splitter was an old UHF/VHF splitter/combiner so one leg wasn't getting the frequencies needed. Just thought I'd mention that here so people here can "file" it in their "troubleshooting guide" as that isn't something I've seen in a long time with 3 coax connections as usually my UHF was 300 ohm when I had them.Edited by signcarver - 2/10/13 at 8:18pm
