I was taking pictures with the camera. When I pressed the photo button again, it shut off and made a sound, like that of a PC shutting down. I tried all my batteries and and the ac adapter. No luck. It doesn't turn on. The only thing it does is the blue HDV and DV lights flash. I looked at the manual and all I can think of is that somehow the internal battery is dead. It said to connect the camera to the ac adapter for at least 24 hours, so I'm still waiting. Has this happened to any of you? What can I do?
