I don't know where and you did apply that high voltage. I except that the charging port and power management IC have been gone in smoke. If you haven't opened your Walkman after the voltage damaged it, possible more components (like internal flexible cable, display, LCD flexible cable, front keypad UI and keyboard UI) have been destroyed. Phones don't have a fuse if it is dead.
