Also check in your Owners Manual and the manufacturers web site for any possible additional information (for example factory reset procedure).
If nothing pans out exploring those venues, then it's repair shop time, or open the unit armed with appropriate test equipment such as a multimeter to preform voltage tests. Of course, your charger should also be tested to see if it is generating and providing the correct voltage(s) to your unit. For further assistance you can report back here on what you have found, tried etc while keeping in mind the statement "I've tried everything" is not an informative statement to use.
