2.8 inch TFT Touch Shield not displaying shapes using Arduino Mega 2560

Hello, I was trying to work through the examples provided with the library found at

<LINK_TEXT text=“http://wiki.seeedstudio.com/2.8inch_TFT … /#features”>http://wiki.seeedstudio.com/2.8inch_TFT_Touch_Shield_v2.0/#features</LINK_TEXT>

The touch screen works fine. However, I can only turn the backlight on and off. I cannot display shapes. Could you help me?

I am using ICSP on my mega and have made the jumper connections.

Thank you.


We just follow wiki and download the example. the tft works well. please provide your detail steps and pictures. thanks.
