Graphic LCD (CGM12864I) problem

Any ideas what could be wrong with my (rather small) 128x64 GLCD?

Initiating the GLCDexample sketch:

The module is using the ks0108 controller and I have connected it to the arduino according to the ks0108 library and the datasheet http://xethic.net/arduino/CGM12864I.pdf
I have tripple checked the wiring, and there are no shorts, and the FPS are showing 8.

Any ideas what could be wrong?

I know my Hyundai HG12605 is the exact same thing as a generic issue ks108 based glcd, but the pinout is slightly different

look on the board and see if someone confesses to making it and check their data sheet

thank you for reply, but I'm using the right datasheet.

I tested the setup with a Duemilanove (DRFduino, that is) and by suprise it worked as wanted! The problem only occurs when using Arduino Nano (v3).

I can confirm that the same you use, I have doubts on the pin, I do not find the data sheet.

Spain Forum answers me with this information.

I hope you find it useful.
