just went to turn on my hero 4 an the redlight is solid on the front an nothing else is working any ideas battey is fully charged havent got a spare battery to try either
you can reset the camera, did you try that?. you can pull the bat and try just ext power. if not then up to you to get a spare and what if it does not fix it?
tried resettting it an external power but notthing will light up on external power
things do give. if you can like said get a aftermarket bat. and see if that workps, you have to see if it is worth the investment. if it fails then it is lost money.
