Important to know the history of the machine, any drops, spills etc. If you don't know the history you will need a schematic, board view and a multimeter and you will want to start test the power rails to see what is and is not present. Once you have narrowed done what power rail is missing you can then begin to diagnose the issue. I have attached the page you need to get started testing start with PPBUS_G3H
