I have tried with the liquidcrystal lib with no success.
I believe that your device is a graphical lcd (GLCD) as opposed to being a character mode lcd, therefore the LiquidCrystal library is not appropriate.
According to the data sheet the controller chip is a SBN1661G_M18-D or equivalent.
Now you have to determine if it is equivalent to the KS0108 or the ST7920 for which there are libraries available.
KS0108 library: Arduino Playground - GLCDks0108
ST7920 library: Google Code Archive - Long-term storage for Google Code Project Hosting.
Hopefully bperrybap will spot this and chime in with better information.
