My Go Pro 8 will not turn on and when it tries to turn on the message turning off appears.
The steps on HERO8 Black - Will Not Power On should help.
If it's still the same, please reach out to our Support Team through https://gopro.com/help/ContactUs
Please have your camera's serial number and proof of purchase ready.
I went through all the steps prior to calling support and then again with support to no avail. Looks like and exchange in in the near future. Thanks for your response.
