HELP: Electrical fault involving an X10 appliance module

["Mark Hindess" <ukha@xxxxxxxxxxxxxxxxx>]

Which is most likely cause of a fried neutral pin on a plug that was
plugged in to an X10 appliance module? The appliance, plug, or module?

For picture see:

Obviously, I'm planning to replace the plug and appliance module, but
I'd like to know if I should be replacing the (expensive) appliance or
at least getting it looked at.

Regards,
Mark.
