No Light Question from a Yocan fan:
The battery will no longer turn on. I have fully changed it, tried a new atomizer and it wont turn on. The white led white wont even come on when you press it. I have only owned it for a week! Is there anything you can do?
If your device has fully charged, and try to turn it on by tap the fire button 5 time in a row.
As your described, there is no light when you tap the button. Please contact the shop to check it is a malmanufacture device or not.
