I have exactly the same problem. The unit was working fine two weeks ago and then suddenly died. Again i have checked fuse leads and changed remote batteries etc but big blue power on light on unit does not display and nothing happens when remote is pressed.
I guess its U/S and time to buy a new one?
PS i live in Kent and we have not had the Switchover yet
Any help / solutions appreciated before i throw it in the bin?
