There is a fuse inside the transformer's plastic housing.  It is possible that
a defect in the 850 blew fuses in both of your transformers.  It is possible
to repair the transformers by gently squeezing the plastic housing at the
joint in a vise.  This should crack the glued joint enough so you can pry it
open.  then look at the fuse and replace it if bad.  
Then the next question is what may be wrong with the 850.  Open the plastic
housing and inspect the power connector for a short.  Beyond this, you'll need
some electronics smarts to find the problem.  Probably a defect in its ac to
dc conversion circuits.
