Hello & Welcome to Just Answer,
I'm Greg and will do my best to assist you today.
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) When was the device last used SUCCESSFULLY?
2) Was it connected to a power source that last time, and if so, what power source?
3) What power source was it connected to for the 4 hour charge time, and when was that done?
