I purchased the Denon AVR-4800 recently and I cannot get the setup menu (not sure if that's different than the OSD) to display on my tv (Samsung UN46C6300SF). I have tried Monitor Out 1 connected to the Composite in on my tv and get nothing. I have also used an S-Video adapter to connect the composite cable (my tv does not have S-Video) but I still get nothing. I have changed the Source on my tv to Component and AV, but it states that nothing is connected.
I currently have all media devices connected to my tv through HDMI, with the digital audio out connecting to the receiver (short term), so no video is going into the receiver.
I do not have the original remote control, so I'm using a Logitech Harmony 650, which may be part of the issue. I am not all too familiar with using receivers, but I am fairly tech savvy. I just need to setup my surround sound correctly, and any help would be greatly appreciated. Thanks!
