Charge 3 screen went blank and it won't turn on

I put Fitbit on charge and held button in to try to reset but as soon as you push the button it starts vibrating and nothing comes up on screen

Hi @Unicorn_mum, welcome to our Fitbit Community! I'd like to follow up and help you with your Charge 3 since the screen went blank and it won't turn on. By the way, thank you for trying to get this issue resolved before contacting our forums.

I'd like you to try a long restart. To do so on your device, follow the steps below:

1. Connect the device to the charging cable. 
2. While the device is plugged into the charging cable, press and hold the button down for 15 seconds. 
3. The device turns on and shows a battery icon. Two vibrations occur: first a short vibration, then a medium vibration. 
4. The device turns off.
5. The device turns on and shows a progress bar and short vibrations occur. The progress bar completes. Note: A total of 7 short vibrations occur. 
6. Remove the device from the charging cable. The device shuts down.
7. Important: Plug the device into the charging cable again 
8. Try changing the clock face to one developed by Fitbit, not a third party clock face and see if the screen turns on properly

Keep me posted on the outcome.
