Boardview archive in RAR format, 189 KB, for board 14060-SA; BDV denotes boardview. The name carries no brand or model, and the SA suffix appears in Wistron-style project numbering, though the scheme was not confirmed here, so check the silkscreen on your PCB. After extracting, load the file in a boardview tool like OpenBoardView or FlexBV to identify components, trace nets and locate test points while diagnosing no-power, short circuit or missing-rail faults on the matching board.
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 @cyberlanelectonik. Enginerys does not host this file.
