The green light above the power button is lit but other than that there are no signs of life. I've disconnected everything I can think of, checked all fuses etc. Does anyone know if this is likely to be a controller problem? Any help greatly appreciated.
    RUK level 2 support were supplying new units free of charge at one point, may be worth going through level 1, asking for a case number and see what L2 say?

    I have an LD425C that was doing the same thing. It was a bad mirror motor shutting down the power supply. You could check it, you should smell it if it's bad.. at least you could mine right after taking the mirror motor cover off.

    Thanks for that, i'll bear it in mind, hopefully it'll just be the customer switching off at red switch that's done the damage.

    Meh, mebbe. There was a time I was fitting one or two power supplies a week to these things, I carried two on my car. A few customers have said they go with a hell of a bang. Not fitted one for about a year now. I think it was just a bad batch of boards.
    It's 106 miles to Chicago. We've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.

    Hit it.

    Found a guy in Manchester who repaired the PSU, he charged us about £100 and it works fine. Considerably cheaper than the cost of a new PSU. If anyone wants his number PM me and i'll pass it on.
