I recently purchased the adafruit 2.8" LCD screen and when I installed it to my raspberry pi B, I would only get a white screen.
I then plugged in my hdmi cable to my monitor and my raspberry pi worked on the monitor but I wasn't getting anything on the 2.8" screen. I would only get a blank white screen. I also tried it on my raspberry pi B+ and I would get the same thing.
Please help.

Have you gone through the installation steps shown in the PiTFT tutorial?

Hi
So I went ahead through the whole coding process and I had two problems.
One, when I enter
wget http://adafruit-download.s3.amazonaws.c ... afruit.deb
wget http://adafruit-download.s3.amazonaws.c ... afruit.deb
wget http://adafruit-download.s3.amazonaws.c ... afruit.deb
wget http://adafruit-download.s3.amazonaws.c ... afruit.deb
wget http://adafruit-download.s3.amazonaws.c ... 0917-1.deb
The last one bootloader was not found and did not load
Also
When I entered sudo mv/usr/share/X11/.......
It said command not found and
Sudo modprobe fbtft_device name=adafruitts rotate 90 device could not be found
Everything else worked out fine
Device still does not display anything

Try using the precompiled disk image. That's our "known good configuration" for testing.

If I need to start a separate thread please let me know, but I am having this exact same issue with my recently purchased screen. Ive tried the script, the detailed install and the image (A couple times each) and all I get is a blank white screen as well.

You're using the image linked on the tutorial page? Do you have the resistive touch or the capacitive touch screen? Are you sure you're using the right image?

I'm having the same problem, only a white screen. I've tried the Adafruit image and tried a fresh Rapbian image with the setup script in the instructions with the same results.

I got it to work! I reseated the flat ribbon cable and the display showed text output as expected. Looks like it was simply a bad connection.
