I have connected the DS-A4 to my receiver via component/composite and connected to my TV via HDMI. I am not getting an on-screen display.
First, you will need to verify that your receiver up-converts to HDMI. Click this link to see the see the status of your receiver http://www.flickr.com/photos/onkyousa_customersupport/7352142678/in/photostream/lightbox/ .If your receiver does up-convert, turn off the HDMI assignment for that input. For example if you are connecting the dock to the “Game” port, you would need to go into the INPUT/OUTPUT Assignment and set GAME to “----“so that the receiver only reads the information from the component/composite inputs.
