Hey PickBricks. Sorry about the late reply. I had this open all day yesterday, but sometimes my browser windows/tabs get out of control and I forget about stuff.
I think the #1 cause of this would be the connector where the LCD's ribbon meets the main PCB. If this isn't fully locked down properly, then it will sometimes work and then, when it gets a poor connection, it will be a white screen.
Here's an old video, but it's still applicable.

The Pi module itself can cause this, but that's rare. You can disconnect the Pi and reconnect it to see if that helps.

The other potential culprit can be the LCD driver. Offhand, I don't recall exactly the steps, but (with HDMI connected):
- When you boot up, go to the RetroPie menu (at the main menu)
- Choose Freeplay LCD driver (depending on which version of the software you're using, there may be a Freeplay menu and then the LCD driver is in a submenu)
- Choose the driver that suits your build (Probably "fast filled" or "fast cropped")
OR (if it's software) just try using a new SD card and burn the SD image to it to see if that helps. Then we'd know if it's a configuration problem.
Let us know if any of that helps.
