Try to make a phone call. If it makes it, then you can start thinking your lcd is going wild.

Hhhhmmmmm. You said you've flashed the phone three times already. Do you use the same MAIN or FS? Try new ones.

Already done, display ok and led ok. Screen blank when press down, after few second keypad light off and when i touch any key screen light up again. So it's become blank when i press down.

it seems that the lcd and keypad is ok....
@edit
#1. remove memory card, use a dummy sim, use only stock drivers, switch on the phone, check if the screen lights up on each button pressed. sometimes faulty external hardware and modded driver may caused blank screen
#2. connect your phone to mpe and use the mpe phone keypad to press all the buttons, if on all pressed the screen lights up then the hardware is not at fault.
#3. open up your phone, check all the flex cable/connectors, clean all dust with a brush or an air blower not cloth and make sure the keypad membrane and the lcd sits in its place. finally
#4. if all the above doesn't work, replace the lcd screen
