Can't really help but I'm awaiting a50FF board. The common faukt with these boards was a burned out resistor in the centre of the board, a common fault and normally it solved the problem. The board I have though has a large burn at the front right side adjacent with the 5 pole connector an seems to be the blue wire connection to the fan. Just hope there is nothing wrong with fan that has blown the board. Fan motor resistance seems OK though. Does your old board show any signs of burning?
