Graphic LCD not working with c8051f120

Dear Friends,

I have just interfaced a lot of devices with c8051f120 (Si Labs) and was doing good but its been quite a long time and i am not able to get graphics LCD 128x64 to work.

I am using 1K pull ups,also how do i execute the status read instruction. It always returns 0x00 on the port,although i change display on / off.

I am not getting any display on it and also dont know if it is executing the instructions i send or not. I have followed the flow as exactly in the datasheet.

All happens is that during power up,all pixels are 1 for abt a milli second and thats it..Sometimes it takes some random instructions and displays random lines..

Pls help..
