By any chance did you remove the polarizing strip instead of just the
thin protective strip on the LCD module?
I did that and ordered a new one. I dug the old strip out of the
trash, cleaned it off and stuck it back on so I could continue
building--it's still there working just fine.

Don,
Cold solder joints galore; it's working now, though the display
still isn't viewable from head-on. Doesn't make a whole lot of
sense, but I can work with it and go on to the next step.

If you do find unsoldered or poorly soldered socket pins, you can
cut away a
bit of the plastic on the side of the socket and get a soldering
iron tip on
the pin to reheat it and feed more solder.
If you suspect the LCD pins, they can be soldered from the top
side of the
board which often provides a better connection since it is
difficult to
properly heat the pins with no projection from the bottom of the
board.
