The signal reaching the box is bad. Check all the cables used to connect the boxes, You might have loosened and end connection on one of the coaxial cables. Also check ends of the cables to make sure middle wire is not bent and long enough, and re-connect them.
If you used an HDMI cable, is it a newer upgraded version?
