There are some other posts here about problems with certain TVs when one box or the other goes into sleep/low power mode and doesn't respond to the HDCP handshake quickly enough when the other needs it. If unplugging and reconnecting the HDMI connection - or perhaps switching the TV to a different input and back - fixes it, that is likely the problem. There are some reports of fixing it by turning off sleep mode on one or both devices, replacing the HDMI cable, setting the X1 box to output 1080p, or getting a firmware update for the TV.
