I'm having the same problem, haven't been able to watch TV since yesterday (Monday July 21st 2014) around 4pm. Got home from work today and turned on the TV, screen was black then no signal. Tried switching HDMI cables, same problem. Even tried plugging the X1 into a different HDMI port on my TV, same problem. But when I plug something else in to the HDMI port I usually use for the cable box, I get a perfect picture... trying to avoid having to call a tech out here as it takes forever for them to get on my base.
