Hi,

Does the tablet charge when you connect the charger and switch the power ON?

If so let it charge until it is fully charged, disconnect the charger, then perform a hard reset which will restore your tablet to its original factory settings.

Here is a link which explains how to do a hard reset for your tab. http://www.verizonwireless.com/support/k...

Be aware of the warning notice in the middle of the page regarding what happens when you perform a hard reset.
