GLCD-T6963C NOT WORK

[SILVESTROS9]

Hello to all!
I would like to display some large characters on a gLCD, a type AGM-2412A 128X240 dots. This display has T6963CFG controller. My goal is to use that display as modbus terminal to send some messages. First I was tried to test the display , so I made a demo code to send some characters to glcd, but the display not work. I use a PIC 18F458, at 16MHZ. The chip works (I test it with a led on-off at one pin), so what's wrong , component macro or demo code? I was inspected component properties and hardware connections to gLCD , but I can't found something.How can I test it? Thanks in advance for any help.
