My Charge 3 shows a black screen

[LauraP15]

Woke up this morning and all I have is a black screen on my Fitbit charge 3. No time or can’t see how many steps I have done. Only had it a few weeks. Need it fixed as I’m doing the one million step challenge for Diabetes to raise money. 
please help ASAP

Welcome to the Fitbit Community @LauraP15.

I'm sorry to hear that your Fitbit Charge 3 doesn't turn on. Thank you for the information provided.

Please restart your Tracker by following these steps.

Besides the regular restart you can also try a long restart by doing the following:

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.

In addition, you can change the clock face of your Tracker as explained in this article.

Whether none of this works, please verify if the device vibrates when you press the button.

If you have any question, please let us know.
