Hi guys! I have a Yamaha RX-381-BL AV receiver output to a hdmi Samsung tv. I have 4 hdmi inputs and 1 rca composite input to the AVR from a karaoke dvd machine. I can’t get the video to display on my tv when selecting the karaoke input. Is there a setting I am missing? I am replacing an older Denon receiver that had no problem. Appreciate any feedback or advice. Thanks!
