My HDR 1800T is having issues , the media list is not appearing on screen when I press the media button , when I try and record something with the record button I get a on screen blue circle. After this Symbal appears nothing records on the device. When I try and access the Data Storage section I can't because it is greyed out. I have already formatted the device. Can someone tell me what to do please or what I can do. Thanks !!
