STM32F769 Discovery kit makes high pitched noise

Dear STMicro,


I bought an STM32F769 Discovery kit but cannot use it for a very frustrating reason. When I switch it on, it generates a high pitched noise driving me crazy. The noise is not loud, but the high tone (high pitch) is extremely annoying.

I think it is related to the display.


Can you please help?
