I bought an HDR-AS15 camera a few months ago and up till now it has been working well. It has developed a problem in that it records for a short time and then shuts down. When I press the record button again it goes into recovery mode and then records again for a short while before repeating the shut down process. On some occassions it wont start recording again at all and refuses to switch on by any means. I have 2 batteries and both are fully charged via external charger and indeed when the camera switches on it will show the full bars. I have tried resetting the camera in the menu to no avail. Can anyone help or have I got a duff camera?
