I had taken the time to make a better overview of the voltages. What is seen on the drawing are measurements which are made when the board were is error state and in working state. What also can been seen is the source for activate most (EN pin) of the Dc/Dc converters, as also the (in most cases) zero 0hm resistors, which may be handy to know when you have one, more or all inactive dc converters. Anyways, it may interesting info when you have a HW issue. Also included several datasheets to make things easier but be aware of that this overview could be changed when there is wrong information on it, or added more or other info. Good luck with repairing.... Click picture for a full view..
