Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) The AGE of the device?
2) WHEN was this device last used successfully?
3) WHEN this issue first began?
Hi again and thanks for that information.
OK - how long was the device attached to the vehicle power adapter?
And what power source was used when connecting to the USB cable?
OK - there is a fuse in the tip of the vehicle power adapter that MAY be blown.
There should also be a power indicator LED in the vehicle adapter - it that LED glowing BRIGHTLY when plugged in?
If so, please disconnect the device from any power connection, and then press and HOLD the power switch - for 30-60 seconds. If the screen comes on, release the power switch.
Please let me know if the screen comes on when you do that.
I didn't see a response back from you last note/suggestion, so I wanted to check back and see if the device came on for you - after HOLDING the power switch, or if there are further steps needed?
I look forward to your reply or any other questions you may have.
