i own a Yamaha RX-V381 receiver. I can connect all my input devices like my cable box and apple tv. I was testing my son's new playstation 4 and hooked it up to the Yamaha, and now it no longer will recognize my cable box. I have disconnected the playstation and re booted everything, and theYamaha still shows the Playstation 4 and no cable box. What gives and how do i fix this?
TV should be plugged into the white/light grey HDMI out port, all other devices should be plugged into the 4 input hdmi. Then from the front you should be able to select what input you want to display to the tv.
