Phantom DVD



I have a DMR-EX77EB 3 years old that indicates on the main display (a white disc icon) that it has a DVD inserted. However there is NO disc, blank or otherwise in the machine. When a blank DVD is loaded the message “This is a non recordable disc” is displayed on the TV, I have used hundreds of the same brand disc’s without any problems. There are no fault numbers displayed. I can still record/playback from the Hard Disk Help please:doh:
