About 3 weks ago when It was very windy, I used my camcorder outside in open air. Somehow sand got innto it. It has caused poor picture and sound. I sent it back to the dealer. they sent it back to me saying \"It is beyond repair\". How is it ? Should it be possible to clean it ? I have to forget my 500 Pound camera just becuase sand got into it ? Should the camera be more robust ? It seems to me very strange. Surely, there are other people who encounter similar problem.
