Are you checking between the 12V and one of these legs? It’s typically connected to ground in these types of controllers. Here’s the SOT23 pinoutfor reference if that is the same package.

According to elegoo’s firmware instructions, the screen itself has updatable firmware too. Maybe you could try updating that as well

I found this diagram for V2.2 which looks the same. The lit LED is D5 which is the one you mentioned on the 3rd page. It looks like it only indicates that the 5V to 3.3V regulator beside it is working and has power.
