Patrick,
Ok, well, don't despair too much just yet - if the display lit up briefly and went away, it's possible that it's a simple battery connection issue.
The battery hatches on these models are a little fussy. I'd focus my efforts there first. Try bridging the connection between the battery and the case with a piece of metal and see if that does anything.
I have some manual pages for this model, but I don't think that they will be of much help. I'll try to get around to posting 'em anyhow since the part about the stem position would be useful to have online.
Good luck,
-abe.
