Hi Mark,
I received finally a set of 10 AMS1117 3.3V.
I place a new one on the GTM32 and 3.3V appears again but unfortunately, once the STM32 boot, 2 - 3 seconds after the board hang up.
Take a look at the video.

Re: LCD or board does not start
Hi Mark,
Yes, 24 VDC and 5 VDC are correct.
On the pin 1 and 3 of the ams1117, 5VDC is there.

Re: LCD or board does not start
Hi Mark,
Exact, I have only 1,4 volt and that is not enough to start the microcontroller.
I will try to find a AMS1117 3.3V and replace it if you agree.
Best regards. Celian.

Re: LCD or board does not start
Hi Mark,
I switched and test the LCD cable. No matter.
As the board is "working" with a correct LCD display for a whole second, i suspect the microcontroller.
I tried to flash the firmware, no success even the STM32 USB device is well recognized by my computer.
