I have a Hero 10 Black.
My Go pro only turs on when I connect it to power, then it proceeds to show 'Cold battery alert'. After it's on while still plugged in, pressing record causes the screen to go blank but it still records everything. And even when plugged in it doesn't charge or show the charging red button.
Can you fix it?

What you're describing all points at power. A "Cold battery" alert at normal temperature usually means the camera is getting a bad reading from the battery. That can be a worn or faulty battery, dirty or bent battery contacts in the bay, or a fault in the charging circuit on the main board. The fact that it won't charge or show the red charging light fits the same picture. The screen going blank when you hit record likely happens because recording draws more power than the camera can get without a working battery.

Try another genuine GoPro battery for the Hero 10 if you can borrow one. If the alert goes away, the battery was the problem. Also check the battery contacts for corrosion or damage.

If a known good battery doesn't fix it, order the free GoPro diagnostic. We'll test the charging and power circuit and quote before any work, and if you decline there's no bench fee, only return shipping.
