    Thanks Jonathan but that is a completely different to mine. Interestingly though you have a large through fuse roughly where my smt one is. If only i could get a rating might give me clue. I'm trying to get a photo up of it now.

    Hmm, that's a bit different to others I've seen. What's the number adjacent to the blown component, 'V?5'? There looks to be a stripe on it, which would imply a diode or a transient voltage suppression diode. Is it in series or parallel with the power input, or something more imaginative?
    Do you know what caused the fatality?
