RAR archive holding schematic PDF material, named with A1386 and K19; the name carries little else, and no brand or board number is stated. K19 resembles an Apple internal project code, but the archive contents should be opened and checked before assuming which device it covers. Once extracted, the PDF can be read in any viewer to trace rails and signals. Match the board identifier on your PCB against the schematic title block before relying on it for repair work.
