Cannot connect to cable box

We recently got Spectrum/Charter cable service. For some reason the Samsung un55mu8000 has decided that HDMI is now connected to our Yamaha receiver even though the unit is turned OFF! I checked the connection and the HDMI from the cable box is connected to the HDMI 1 port on the connection brick. What gives? The poorly designed Samsung remote will turn on the Samsung DVD player with NO action from the user.  When I go to Source, even tho it shows the Cable Box on HDMI1 it opens the DVD player. HELP!
