I am unable to get my Pi 3B to work with a 3.5in RPI Touchscreen LCD v3.0. I have NOOBS and the Raspbain OS Image downloaded to my micro SD Card. All it does when I set it up is turn white. What is the problem?
Depending on what LCD screen you have, the following may work. First check if the display looks like the picture here. There are many cheap clones of these available on Chinese sites. If it looks similar, first download the correct driver:
For 2016-May-10-raspbian-jessie or later:
For older jessie versions:
After downloading do the following:
tar xvf LCD-show-160520.tar.gz cd LCD-show/ sudo ./LCD35-show
It will reboot and if you are lucky you might have a working display.
