Hi STM, 

I really need your help. I have been trying non stop for the past 5 days just to display something on the LCD.

Step1: I am able to BLINK LD2, LD3 on the board. 

Step2: I want to display something on the LCD. But seems like it is always black. I tried using touchGFX & IDE to display a button, it has no error. but the screen is the still black. https://youtu.be/AizWAlbU4Og?si=uYhhPJ3NZQZXQRtD

Someone please help me to at least start. 

JP5 is connected. 

JP2 pin3,4 is connect
