FWIW, Brighthouse is remapping several QAMs this week. If you have a CableCard, its probably going to go blackscreen on 36 digital chanels.
The easiest way to reset it is to eject and replug in the cablecard to make it acquire the new mapping.
<<snip>>
The only expected and unavoidable residual impact from this maintenance is to CableCards. The affected channels will probably show up as blackscreen to CableCard TV’s until the customer goes in to the settings on their TV and instruct the TV to re-read the revised SI data the DNCS is now sending. This is done by selecting “Channel List Reorganization” (may be called something else or not available; varies by TV make and model), issuing a CableCard reset (less recommended as this can cause more problems for some TV’s), or even by simply ejecting the CableCard from the TV and reinserting it. Powercycling the TV alone will probably not help much. This residual impact was listed in the maintenance ticket. DHCT’s are not affected by this problem as they constantly monitor the OOB SI data for updates and changes in the tuning tables and apply them as soon as they process the updates broadcasted from the siManager process on the DNCS.”
