RPi Display Showing White Screen of Death

Hey all,
I have an official 7 touch screen that suddenly stopped working. I’m reseating the cables multiple times, but I still get a white screen on boot. I even tested a different LCD to rule out the display, but it shows the same white screen.
Is there a way to test the driver board? Should I try getting a new driver board to see if the LCDs are still good?

@mercy-joyce, I’d like to ask for the following details:

  • Raspberry Pi Hardware Version (e.g., Raspberry Pi 4 Model B)
  • How did you install Anthias?

Given the details that you’ve provided, it might be a general Raspberry Pi issue, or it might be not, so I asked for details.

Thanks.
