    It's dead. Blank. Nothing happening.

    With battery power connected, try pressing each button very firmly. If it still does not power up, then it is likely it is internally damaged.

    There is a common repair for faded LCD digits (see the MFD section from my signature links) but not for actually repairing the electronics inside when it is totally dead.
