Hy
I just got the new 2.8 TFT Touch Shield from SeeedStudio:
http://www.seeedstudio.com/depot/28-tft-touch-shield-p-864.html?cPath=132_134
First I used the sketch below which worked great. Then I added a few Rectangles and
more circles but suddenly the Screen stayed white even after disconnecting from the Arduino
and reattaching.
I then just tried the example sketch but the Display stays white....
I tried several things but still it won't change anything... Is the Display already dead?

void setup()
{
Serial.begin(19200);
Tft.init(); //init TFT
Tft.drawCircle(100, 100, 30,YELLOW);
Tft.drawCircle(100, 200, 40,CYAN);
Tft.fillCircle(200, 100, 30,RED);
Tft.fillCircle(200, 200, 30,BLUE);
}
void loop()
{
}
