Thanks to everyone on the thread for your advice. I did open up the RCX and did
not find any more battery gunk.  Everything looked okay, no obvious signs of
damage.  Since this is a newer unit, the battery tabs are soldered to the board.
If I place a meter on the + and - terminals, it shows a short.  If I place a
meter on the output of the voltage regulator and - terminal it shows open. So I
believe the problem is downstream from the voltage regulator.  The large 1000uf
Cap looks fine, no bulging or leaking. I don't think there is a way to test
in-circuit.  Anyway, I will call Lego on Tuesday and see what they say.

Thanks again,
Louis Davis

PS - I will post back to the list with the results.
