Problem with LCD3310

[sandro]

Hi,
I'm using a mod-lcd3310 rev A.
The LCD works fine, but I can't see the first 3 lines and the last rows are full of casual dots.
I found some discussions of this problem (for example http://www.edaboard.com/thread132496-2.html).
I solved the casual dots by changing the lcd resolution's from 84x48 to 102x68.
But I can't see again the first three lines.
I tried to use the command

LCDSend( 0x45,SEND_CMD );

like is suggested on the forum but it haven't effect.

Someone can help me?

Thanks
Sandro
