Boardview for an Apple iMac logic board numbered 820-2301, provided as a BRD file inside a 127 KB RAR archive. The 820-xxxx format is Apple's own logic board numbering, so the number on the PCB is the key reference when picking the right file. Load it in a viewer like OpenBoardView or FlexBV to find components, trace nets and locate measurement points while diagnosing power or no-video faults. Pairing it with the matching schematic makes rail tracing much faster, but confirm the board number first.
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 @schematicslaptop. Enginerys does not host this file.
