Ah...well, the display didn't light up eh? Well, I'll bet you did scrape
off some part of the board because the EXACT same thing happened to me and
this is what I did: I traced the connection back to the main chip (the
large one) and soldered a wire connecting the capacitor to the left of C9
and to one of the pins (I forgot which one: just trace it back on the
board) on the surface mount chip. Then, since I was implimenting a switch,
I soldered C9 backwards (so only one of the contacts of the capacitor is in
its original placing) and soldered a wire on the other end of that and
soldered another one on the wire connecting the other capacitor with the
large chip. I put in the switch and...TADA! It works!

: Okay, so I completely remove C9 and the calc doesn't work
: at all now. I put it back in, still doesn't work. Has this
: happened to anybody else? (before I go out and blow another
: hundred bucks on a calculator!)
: BTW--yes, I do know what I'm doing! This is my first
: experience with SMT, but not my first with solid state
: electronics by any means. No, I did not fry anything with
: the soldering iron! (Unless I maybe scraped some traces off
: the board...)
: Anyhow, anybody had any problems with just plain operation
: after taking out C9?
