I have been in touch with them and this has ended with EMEA support sending me a replacement SB3. Partly out of idle curiosity, and partly due to some enforced idleness caused by a bout of 'flu, I decided to track down the cause of the problem. It appears that the switch mode regulator (NJU7630) that generates the supply for the CPU has failed, as the output is now stuck at the supply voltage (5V) regardless of the input. The end result is that Q3 was passing about 2.7V to the CPU board, hence the hot CPU and the very hot Q3 due to the excess current it was passing. This is probably not directly repairable, as the regulator part is not available retail and even if it was, it hard to say what other damage may have been caused.
