Boardview for Apple logic board 820-01700, with the LO25 label in the name, in BRD format inside a 304 KB ZIP. The Mac model is not stated, so confirm the 820 number printed on the board matches. BRD boardviews open in OpenBoardView, FlexBV and similar tools and show part placement, net names and test points on both sides of the PCB. Use it with the matching schematic to find components, measure rails, check diode readings and trace a short to the part that is pulling it down.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @pepeelectronica. Enginerys does not host this file.
