Hello & Welcome to Just Answer,
Sorry I didn't see your question earlier and to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) What power source did you use to charge the device?
2) Did you remove the power source BEFORE attempting to power the device ON?
3) Did you VERIFY that the charging source was actually supplying power (if using the vehicle power adapter, some vehicles MUST have the ignition turned ON)?
As a FIRST STEP, please remove the device from the charging power source, then push and HOLD the power switch - for AT LEAST 30 seconds - OR until the screen comes on.
If the screen DOES come on, release the power switch and allow the device to power up.
Please let me know the answers to the questions above, and what happens when you try to power it ON - as described above.
Thanks, ***** *****
