2.8" TFT Displays All White

My TFT LCD module currently displays only white screen (default screen) even I have uploaded the code on the Arduino IDE. It still displays what I have coded the last time I used it, but now using the same code, it dosen't display anything except for white screen.

Your display knows more than we do!

  • it knows what display it is
  • it knows what controller it has
  • it knows what kind of interface it has
  • it knows what signals it receives (what signals your program produces)
  • obviously it doesn't know what to display, but neither do we.

Your display can't read.
It can't read How to get the best out of this forum.
But maybe you could.
