The Arduino 2.4 TFT Touch shield white screen error

Hi,
I recently bought The Arduino 2.4 TFT Touch shield from http://www.electrokit.com/2-4-tft-lcd-touch-shield-for-arduino.49420 with Arduino Uno
but I have trouble with white screen. The Arduino 2.4 TFT Touch shield uses the S6D1121 controller , it support 8bit
data interface. The touch IC is TSC2046 and I have followed schematic and download UTFT library for Arduino. This white screen is still there and help to solve this problem.

Solved problem with this code UTFT myGLCD(ITDB28,A5,A4,A3,A2);
