I know TWC techs read this board,
Please monitor picture quality on HD channels 1005 and 1012. (Local stations, channel's 12 and 58.) Several neighbors, friends, and our family, will from time to time get a black screen on these channels. The problem is very intermittent, but seems to happen most often on weekends and during the overnight-early morning hours between approximately 2-6 am.
The SD versions of these channels on 6 and 12 are not affected.
The signal will than come back, and than 2 weeks later go out again, and it always seems to be at the times indicated above. I have learned that these stations' frequencies are very close together. Today, both of them were out at the same time.
I am in the Metro-Milwaukee (Brookfield) area. Please check these channels regularly to address the issues. It has been like this for several months. My older box did this too, so it has to be something on your end.
