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