Eric,

I just got the LCD module working. I swapped the contrast and +5 pins,=20
so... connected PIN 3 to +5 volt and connected PIN 2 to contrast and adjust=
ed the pin2 volts to be slightly below the 5V.=20

The LCD works fine now, I suspect that the contrast needed to be higher tha=
n supply for some reason on this LCD who knows.

Hope this helps you get your LCD working

Jay

Unfortunately I don't have a solution for you, but can offer you the piece =

I remember reading the datasheet for this LCD's HD44780 'compatible' contro=

 this
display.  I didn't find any, but it's very possible I overlooked something.
