Hard to be sure without seeing it in person, but if you have checked that the cable is fully plugged in the back, checked the fuse in the plug (as UK plugs have fuses), tried it on a different wall socket, and there is no light on it at all then it must be dead. Jim.

Thank you Jim. As I suspected. Now got to decide whether its worth trying to get repaired or replacing. Craig.
