Bachmann 63754 dead on arrival

[ripvanwnkl]

I just bought this new Bachmann #63754 Erie Lackawanna F7A with DCC no sound from an online hobby shop in Maryland.  It was dead on arrival.  Loco looks fine but won't respond to any commands from my EZ Command.  I have four other F7As from this same line (SNs #63751-55) which work fine with the same EZ Command and track.  Any suggestions before I send it in for repair/replacement? 

Thanks.
