Don't get all bent out of shape yet you might be able to fix your neon.
Remove the cover and take a look and see if it has black tar inside the neon
transformer case.  If it does then put the neon in your kitchen over on
about 150 deg.  After 1 hour check to see if the tar has melted.  If not
turn up the tempature 20 deg every 30 minutes until it melts.  Stir the
melted tar around a bit then let it cool and the neon will usually work
fine.  I perfer to mix the liquid tar with 25% high voltage oil it make a
more bullet proof neon transformer.
