I just purchased the Adafruit 3.5" 320x480 Color TFT Touchscreen Breakout. It is defective and does not work. I first wired it in 8 bit mode, followed all directions, imported all appropriate libraries, etc. I uploaded the sketch to an Arduino Uno, and the screen remained white/blank. The serial monitor said unknown driver.
I then tried the SPI mode, shorted the jumper, installed appropriate libraries, wiring, etc. I still get a blank screen. This is what the serial monitor says:
HX8357D Test!
Display Power Mode: 0xFF
MADCTL Mode: 0xFF
Pixel Format: 0xFF
Image Format: 0xFF
Self Diagnostic: 0xFF
Benchmark Time (microseconds)
Text 2029072
Lines 6344924
Rectangles (outline) 253428
Circles (outline) 2710176
Triangles (outline) 1774716
Triangles (filled) 4901776
Rounded rects (outline) 685524
Rounded rects (filled) 9457644
Done!
I've spent hours rewiring, new wiring each time. I've tried 4 different PCs, Arduino IDE 1.0.6 and 1.0.5. I've tried 2 different Arduino Unos and an Arduino Mega 2560.
I've redownloaded the libraries from the web and reinstalled. Nothing has worked. The screen remains white/blank. I would appreciate a replacement as soon as possible

I had the same problem it wasn't till I unplugged then plugged the USB back in that it started working. Also I had a bad solder connections on the End Ground Pin. (Far left or Right depending on how you hold the board)

Check GND and VIN (ground and 5V input), they should be not connected well to pins.
This happened to me also and fixed by re-soldering the VIN and GND pins.
Also, If you are using SPI mode, don't forget to soldering the back of board (there is a small bridge which need to be soldering for SPI Mode).
