No image on screen or in viewfinder

Hello all We have a JVC GR-D32 Mini DV Camcorder. Unfortunately, we have lost the manual for it and have run into a problem. When we turn on the unit, in either "A" or "M" mode, both the digital screen and the viewfinder screen remain black, with no image other than some icons and the date/time. It will flash "lens cap" for a couple of seconds after you power up, but then it goes off (to answer the obvious question, yes the lens cap is off). There is also a small yellow blinking icon on the bottom centre consisting of(in this order,left to right)the figure of a man, two arrow heads pointing in opposite directions, then what looks to be a castle turret.This flashes continuously, and does not go off no matter what setting is tried. When I put it in playback mode, and put in an old tape, we can watch what we taped previously, so it isn't the screen itself. We have tried adjusting every setting we can, with no luck either. To our knowledge, the camcorder has not been dropped, or otherwise abused. Thanks for any help anyone can offer
