R80b400 pandigital supernova tablet wont turn on it just flashes the pandigital screen on an off

SOURCE: have a white screen on tablet can' turn off nor on pandigital

Very gently unplug the battery cable for two minutes.. I used a pair of tweezers and worked it out. Plugged it back in and it is fine. What a relief. I have read that if it goes to sleep while plugged in via usb, it freezes? Don't know. Just be careful when pulling the battery!

SOURCE: the touchscreen wont work on my pandigital supernova tablet how can i fix it

Sounds like an internal issue. These things are touchy so unless you feel confortable if you accidentally break something while trying to fix it then I would get a tech repair. With the price of these kinds of tablets though you may be better off getting a new one. New Kindle Fire is 150 now :)

check the manual if you have it

SOURCE: I charged my pandigital supernova. I went to turn it on and it keeps flashing the word pandigital. What do I do?

Same thing happened to me. All you can do is return it and order a new one free of charge.
