Strange white light
After fixing usb charging port on mz615, i have a problem. When i plug it to charger, the white light is turning on for a while -est 5 min and then it is turn of. I think tablet is not charging, because when i tri to turn it on red light bilinking 3 times and nothing happens. I have tried power button + volume up, volume down ... everything but nothing changed.
Do u have any idea? Is battery death or something bigger problem?
