I agree with Geoff about turned pin sockets, they are worth the money, but
they require a lot more insertion force. Ensure all your pins are straight
and exactly aligned with the socket before re-inserting or there is a
distinct danger of folding a pin up under itself and this is sometimes
difficult to spot. I've fitted several thousand, I have the scars!

In both cases the problem was caused by the socket of U6 the Control Board
MCU, pulling U6 and reseating it cured the problem. After the second
episode I replaced U6's socket with a 'Turned Pin' type which I should
have used when building the rig. The type of socket supplied with the kit
can often give rise to 'corrosion' problems, which result in poor contact
between IC pins and the IC socket.
