Thanks for your answer :).
However it did still not works for me...
disneysw:
To do this modify "Adafruit_TFTLCD.cpp" and replace the array "ILI932x_regValues" with the following:
...
Then in your setup code use: "tft.begin(0x9341);
I replaced ILI9341 values and I am still getting a white screen....Later I tried to use ILI932x values and only got a white screen...
Could you send me your hacked TFTLCD library please so I can be sure if my screen is defective or not?
Anyway thanks a lot for your answer
