I am currently using STM32F469 discovery board , previously the screen was working fine as it was displaying TouchGFX demo as soon as it was connected, now only LD5 and LD6 LEDs are turning on , any idea on how to make the screen work?

IDE being used is SW4STM32

Hi. Perhaps the code was erased or kit was reflashed?

You should be able to locate or download the compiled binary (.hex) file for this demo and reflash the kit again using ST-Link Utility tool from here:

https://www.st.com/en/development-tools/stsw-link004.html

Run this tool -> Target -> Connect

File -> Open -> select the .hex file you wish to upload to the kit -> Target -> Program

Press RESET button on the kit.

Post your update after testing.
