Probably one (or more) of ceramic capacitors gives short to ground in power line.

I've had two similar problems with a D600. Both times it was diagnosed as a motherboard fault , changed once under warranty and on the second occasion it cost me serious cash. I'm not sure whether this really was the problem or whether it's the stock remedy for similar fault. I was told by the 'engineer' on the first occasion that D600 boards were prone to failure.
