For DirecTV TV services which include DVRs and receivers, Color fades to black and white during hockey. i have an LG smart TV. AT& T U Verse cable package. I watch Detroit Red Wings hockey on channel 737. The picture fades from color to black and white and then back to color again very frequently during games --every minute or two. Sometimes it will stay color for four or five minutes, but it fades out very often. It does not stay B & white very long--usually a minute or less, but it is VERY annoying. It does not ever happen on any other channel besides 737 and only during hockey games. Do you know what is causing this?
