Thanks for the trouble shooting tips. The smell and color reminded me
more of frying resistors :-) I haven't opened her up yet to peek at
the damage.


Pull the case open and look inside! If you see some big resistors in
the power supply gone open, check the capacitors downstream of them for
a dead short. You'll never know until you open it! They are fun and
easy to work on... everything is laid out very openly and the basic
design you can figure out by looking for the most part.
