MFD12 Shut Down won't Start Again

[carstenb]

My MFD12 suddenly shut down as I was entering a harbour and won't start up again. I've checked the power at the power line inlet (after the fuse) and it shows 13.1 V - so plenty of power

any help?

It sounds like a serious failure, maybe the internal power supply. I would send it in or take it to a dealer for evaluation.
