Black screen

[Mingor]

Couple days ago the screen went black and 

I’ve tried the troubleshooting whit tapping three times. I can feel it vibrating when I tap and once a couple of seconds later. But there’s no Fitbit-logo showing. 
Also tried changing the clock in the app. It work for few seconds and turn to black screen again when I put it down. Already follow all the step to reset my charge 5 but still the same. What should I do now?

Welcome to the Fitbit community, @Mingor!

Sad to hear that you're Charge 5 isn't working as expected. As timing is important while restarting your device, please give it another try closely following these instructions:

1.) Connect your Charge 5 to the charging cable which has to be connected to a power source.

2.) Press the button located on the USB plug of the charger 3 times within 8 seconds(!), holding each press for about 1 second(!).

3.) Wait around 10 seconds until the Fitbit logo appears.

If that won't solve your issue, I'd suggest contacting Fibit  support to get further assistance:

Hello Talahthas,

Thank you for your reply. I already tried this more than 10 times. I follow all the step you told me and the Fitbit logo came up again, but when I put it down my Fitbit, it became to black screen in few minutes. I don’t know what wrong with my Fitbit.

Thanks for your fast feedback, @Mingor, although I would have liked to hear something different, of course.

It's possible that your Charge 5's battery is almost drained. Have you tried charging your device for several hours with a proven power source?

Please also check this article to make sure your device is really charging:

Sorry to say, but I'd conclude that your Charge 5 seems to be defective, @Mingor. Thus I'd suggest contacting Fibit support to get further assistance:
