No image, only sound when
Whatever video components you have, they should be, depending on inputs on TV, should be run to TV first. Recievers do have pass through ports but, are not the best way to achieve picture and sound. HDMI cables are great but you r reciever may not be able to transfer the video. What I suggest is taht you run your componenets, cable/sat box, DVD, etc. via HDMI, componenet, etc., to TV input, then, run audio out from TV, via(best) digital optical. You can use TV's menu to choose what you watch while, you only have the one input to reciever. Scan your recievers menu to make sure you have selected the proper mode(TV, Aux, Vid2, etc.).. If you run your video unit to TV with component cables, you will have to get your sound through separate cable(s). Component cables have graet video, but do not carry the sound.
