We tend to keep the bathroom light on all night in case of our daughter's sleepwalking. I woke this morning to discover all the upstairs lights weren't working and assumed a bulb had blown somewhere and tripped the fuse box. This is not a rare ocurrence (we lose a light bulb about every week or so).
Looking at the fusebox, the switch for upstairs lighting had indeed tripped. But when I tried to flick it back on, the result was an electrical bang somewhere in the circuit and the lights stayed off. So we are currently facing Christmas without lighting upstairs.
Does this sound like we just need a fuse changing, or do we need to call in an electrician?
