PickBricks,
I re-read your first message and now see that you said you got a "FreePlay Zero CM3." In my reply, I had assumed that you had a Freeplay CM3. Now, I see, that you did say "Freeplay Zero" later. If you have a Zero, then the soldering on the Pi itself can definitely be a culprit for a white screen problem.
It can also be that something is contacting something else.
Basically, if everything else (button controls, green LED, audio, etc) is working properly, the white screen means that data is not getting from the Pi to the LCD. That could be the driver (like we mentioned) or it could be a connection problem.
A bad connection could be in a few different places.
1) Where the pins solder to the Pi
2) Where the Pi pins plug into the Freeplay board
3) Where the LCD plugs into the Freeplay board.
I think you already checked #3. To check #2, I'd probably just pull the Pi off of the Freeplay and then re-insert it.
For #1, maybe show some photos of both sides (the "back" where the pins are soldered being the most important) of the Pi. Often, this is a pin that's either not fully soldered or some solder that's touching something it shouldn't.
YES, it could be a problem on either circuit board. It's unlikely to be the Pi itself, but I will say that we have had a few people get new Pi Zero and that fixed things. In the same way, problems on the Freeplay board are rare, but it could be an issue there.
