I recently got a touchscreen, and found it was white, in another post I mentioned this, and so I got my screen replaced to find the new one also has the same results!
To see if I could find the issue, I grabbed an extra SD card and created a fresh install of noobs. The problem remains.
However, when I put the SD card in my pi1 b+, the screen works fine!
It appears that my screen doesn't work on the pi2. Why?
