Its odd that it just died like that
check if the wires have been squozen or if a connection has come loose on the board.
don't just go out & buy a whole new one, whatever's happened you can replace the one broken part eg board or motor, or resolder a connection etc
if you can take it apart totally to check all connections, wires etc then do it, if you can't/dont want to take it to a pb shop & they'll prob be able to sort you out.
