I recently got a new LCD TFT Display Shield and when I try anything it only shows white! I can use the touchscreen library with no problems and can get coordinates but i can't show anything on the display! I just tried with the ADAFRUIT library and another one called TFTLCD. 
Can someone help me?? It shows C0C0 as my driver chip and says it it unknown!
I hoped to use this but it won't work either:
