Hello Adafruit!

I have Problems with my 2.2" TFT w/ILI9340C. I added the libraries Adafruit_ILI9340 and AdafruitGFX, I can compile and upload the sketch graphictest without problem.

You need to add a jumper wire between VIN and BL to power the backlight.

I can't see any of your solders in the picture - if you can post a picture of those, we can check to see that they are solid.

I can't see how you have the header pins installed, but it looks as if the black plastic is on top of the board, and the long side of the pins are pointing upwards? If so, the pins on the bottom of the board may not be long enough to make contact with the breadboard.

Please post photos of both sides of the display board.
