How to approach it
Current draw with the board off always has a culprit: a blown capacitor, a shorted chip or a leak. First identify the affected line in diode mode (the one reading near 0 or far below the board file), then locate the component by injecting a low voltage with a current limit: the one that heats up first is the suspect. Never inject more than the line's nominal voltage.
