Hi,
I just received my first order yesterday...yay! I'm real happy with everything except the 2.8" TFT Touch Shield (https://www.adafruit.com/products/376) isn't working for me. Could I please ask for your help?
I've followed the tutotial at http://www.ladyada.net/products/tfttouchshield/ installing adafruit-TFTLCD-Library-59e176c.zip and uncommenting (defining) USE_ADAFRUIT_SHIELD_PINOUT. Running the graphicstest shows "Found ILI9325" on the serial port but the LCD just displays the white backlight with no picture. I've put debug messages before each delay in graphicstest and it shows the test code is actually running. I was using an Arduino Pro (328 @ 5V) but also tried a genuine UNO with the same result.
The paint and bitmap examples compile and run, the bitmap inits the SD ok, and reads the tiger bitmap without error (in 2922ms it says), but still no picture.
Am I missing something obvious?

Re: 2.8" TFT Touch Shield has no picture
hi! thats a little unusual - we do test each shield twice before shipping
lets start with a real UNO
plug is in, run tftpaintshield
anything happen?

Hi,
Running tftpaintshield the display just shows the white backlight with no picture. On the serial port I get...
Paint!
Found ILI9325
So it looks like we're talking to the controller ok. I uncommented the x/y/pressure print statements and the touchpad is working fine even without removing the screens protective film. I tried the "bitmap from SD" example and it finds and reads the file from the SD card.
There isn't any wiring to get wrong so i'm a little stumped on what to try next.
Sorry, I'm on the other side of the world so my forum post/reply latency is higher than you might normally expect
Thanks for your time

OK that is odd but perhaps something broke in shipping
email support@adafruit - ask for a new shield

Just got my replacement, and just in time for Christmas Works perfectly with the Arduino Pro (328 @ 5V).
Wow...the display is really vivid...simply beautiful.
Thanks lots

Hi,
I'm having the exact same problem with an Arduino Uno and the 2.8 Touch Shield. When I run the tftpaintshield example only the white background appears and on the Serial monitor I get
Thanks for your help!

With the graphicstest example I get the white background and on the serial monitor:Paint!
Found ILI9325
Was there ever a solution found, or should I return this shield for another one?8 Bit LCD test!

Thanks for your help!

Re: 2.8" TFT Touch Shield has no picture
Okay, it looks like the problem has already been addressed but here it is again. I set up the 2.8" TFT Touch Shield from you guys on my UNO and everything works great minus the pressure readings. However, when I put the shield on my new Arduino MEGA 2560, I can't get the screen to do anything. When I run the tftpaintshield sketch it says
"Paint!
Found ILI9328"
on the serial monitor.
I can also make it say erase by touching the erase side of the Arduino MEGA. In fact, none of the example sketches seem to make any difference. I just can't make the screen do anything is the problem. Thanks for your time.

Re: 2.8" TFT Touch Shield has no picture
OK great. please delete the TFT library and exmaples and redownload from github - we had to update the optimization code for '128 & '256. make sure to completely delete the old version. let us know if it doesnt work now
