Samsung service archive for the P901 model, a ZIP of 8.00 MB. The name gives no hint of what the archive holds, so it may be schematics, layout drawings, a service manual or firmware. Open it and review the files before planning a repair. Service documents of this kind help identify components, follow power and signal paths, and find the test points needed for diagnosis. Make sure the model code and board revision of the unit on the bench match before relying on any value inside.
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 @esquematicosparatodos. Enginerys does not host this file.
