Has anybody any ideas on why the JCM note acceptor in my Enhanced Rio might have stopped working please?
It's been fine and then suddenly the lights on the front don't light up and it won't accept notes.
When I put it in test the lights illuminate and it accepts all notes correctly, but as soon as I close the door it's dead again.
Nothing on the machine has been changed and on switch on it initialises like it's always done, but once machine has finished booting.... nothing 
Been messing with it for well over and hour but can't get any joy, there's no trapped or dodgy looking wires, so I really have no clue as to what's gone wrong.
Thanks
