Schematic PDF named only 6002 series, with no brand, model or board revision given. The 3.72 MB document could belong to a chip family or a product range of that number, so open it and check the title block before relying on it. Schematic PDFs are read in any PDF viewer and used to follow power rails, signal paths and part values. Searching the text for a net or reference designator speeds up fault finding. Match the drawing against the actual hardware before replacing components.
