I recall reading somewhere on the web about a reprograming sequence for the Levinsons, do a search, or perhaps someone knows the location and/or sequence. You may want to call Levinson about the sequence. I have a Proceed CDD which has had some strange readouts a couple of times when connected to a PS300 power condtioner at settings other than 60hz. It seems I also recall unplugging power cord while unit was on and it reset itself. Also, check all the connectors inside for a secure fit, I had a display connection somehow come loose one time. Hope this helps.
