So a very gentle tap on the desk and et voila - it's back !!

My own 34C (and I think another of my Spice models) has the same issue. It's not so severe that I am inclined to open it up, yet though. I need to learn the technique on an otherwise-dead 38C, which is (especially since not-functional) a lot less valuable than the 34C.

I love that L.E.D. glow... so nostalgic and easy on the eyes.
