I have just gotten my Coby Kyros MID7125-4G. It was working fine until two days after Christmas. It would not turn on, It would not respond. I reset it and it did not work. I have gotten to turn on and boot up to the lock screen but it only is able to do this on the charger. When the tablet is on and charging, it is fine. But when i unplug it from the charger, it turns off and resets itself. It wont boot to the lockscreen off the charger. it just continually resets. Can anyone help me?
