Switch your multimeter to continuity mode. Ground your black probe. Touch red to the large inductors (PL1, PL2, etc.). The Boardview will show you which rail is shorted to ground (e.g., +VCCORE ). Look for cracks
If your downloaded Boardview file shows blank rectangles instead of pads, change the rendering settings from "Colored by Layer" to "Monochrome." Is there a PDF Schematic for MB 15256-1? Yes, but with a catch. The schematic (usually 50+ pages) is available alongside the Boardview. However, many PCB manufacturers only leaked the Boardview, not the schematic. If you search for "Brittle MB 15256-1 schematic PDF," you will often find a generic Quanta document. | Software | Best For | File Compatibility
