Lattepanda fails to start after system firmware update

My lattepanda worked find until i checked for a System firmware update.
An update was found ans installed successfully, but after shutdown the system no longer starts up. The display remains black, even no bios setup is available.
Is there any possibility to reset the system firmware?
Please help!
