Facing TV Problems? Ask a TV Technician.
Welcome to JustAnswer.comSorry to hear that you're having trouble with this and I'll do my best to help
- What video devices/ sources (such as cable box DVD player etc) are connected to the TV and does the problem occur on all video sources connected to the TV?
OK, when do you get mode not supported message?
Playing Bluray or watch Xfinity channels?
