I bought my first GoPro this week, a GP3 Silver. Put in 32GB SD card, charged battery, took just one photo.
Now it won't turn on at all. Battery voltage is fine. If I plug into a PC I get a "device not recognized" message and no connection. Plugging the SD card directly into the PC I can see the photo I took.
Camera, however, is completely inert.
Before I send it back, any suggestions? Have I missed something?
