 Bigger Bigger  Smaller Smaller  Reset Reset

Hello all,
I am using a Duemilanove and 128 *64 GLCD but I am unable to start my GLCD - bought from sparkfun. I have the backlight on after the connections but I am not getting any characters printed on it at all. This is my GLCD:
I have made connections as shown for Panel A here:
Despite the connections and hour-long efforts, nothing at all. I have tried several libraries like KS0108 and GLCD library. But so far, i m unsuccessful.

Please help me out here folks.

Are you running the newest ks0108 library?
The GLCD V3 library that is beta.
That library has a diagnostic sketch that sends information
to the serial port that is helpful to see what is going on.
If you can run that sketch and post the output here so I can
take a look at it.
