I'll be damned if I can figure this one out. Can anyone help before I call Marantz? When I try to turn on my OSD using the remote (the only way to turn it on, I think) I get a high frequency noise and white snow in lines on a black background across the TV screen. To get rid of it, I need to power the receiver off and back on. If I change sources without trying the OSD, I get the normal 5 second or so display listing the source and surround mode. If I seclect DVD as a source without the DVD player on, I also get a black screen with similar snow/high frequency noise. In this case it goes away if I pick another source or turn on the DVD player though. Any suggestions?
