one thing you should try first is cut power when you hears sounds if sounds died immediately your battery is DEAD! you can try charging battery and then try again!
you might try a conventional reset while powered up and not moving, if it resets you'll hear 2 whistle toots. if it wont reset board probably needs repaired if you can find one it is a ps 2 3 volt board inside the engine or tender! p.s did you charge the battery before you tried the engine?
