Why won't my GoPro power on?
No matter what I do, my GoPro will not power on at all. What can I do?
The GoPro Hero3Plus Black Edition can be identified by its model number: CHDHX-302. It's an eighth generation camera that was released in October 2013. The GoPro Hero3Plus Black Edition is a Wi-Fi capable, 4K resolution digital camcorder.
This may be as simple as the GoPro doesn't have enough charge. When charging ensure that the display is off and that the red light on the front is solid. Leave it to charge for a few hours and it should be fine. For more answers visit the GoPro Hero 3+ troubleshooting page: GoPro Hero3+ Black Edition Troubleshooting
