Hey, sorry if I've given you a bum steer, RN. Like you, I was convinced that only the A-Board could cause it.
It may of course be a false code.
Do you still get code 14 if you disconnect the SN board from the power supply, otherwise I'm at a total loss.
This is the only bulletin I can find for this model but it doesn't sound like your problem.

Hi Bruce - no worries re A-Board. We live and learn.
Still getting code 14 after disconnecting power from SN board.
Could it be that power board is faulty? supplying power to parts of the set, but not to others?
Could the IR or Buffer boards be faulty?
Is my only option to replace all boards one at a time?
Thanks again for your help - Roy

RNRepair:
one last shot in the dark: is it possible for the power board to be faulty in such a way, that when the A-Board is replaced, the power board causes immediate damage to it (the A-Board)?
