i got my cam in december of last year it is a JVC GR-DX97U, i was using my camera for about 2 hours last night and then i started agian today, for about a half hour and i was making a film, i took it out with me not filming and went to the store and to have dinner and it was in a bag with clothing so it was alright, when i got back home i wanted to go film agian and i tried to start filming and it stays on a black screen and says nothing but "lens cap" and the lens cap was removed and it had no picture so i started to film and i played it back and could only hear audio this is the same with the memory mode, it shows what i filmed earlier, and everything is fine butwhen i try and record it get nothing but audio, whats wrong?
