First part of a Sony K700 schematic set, a 1.02 MB PDF. The name gives only the model and a sequence number, so open the companion parts to see which circuit sections each file covers. These diagrams help trace supply rails, check charging and keypad lines, and find the component behind a no-power or no-signal fault. Any PDF reader will display it. Confirm the board markings on the phone match before relying on part references, as hardware revisions can differ.
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 @mobileshematic. Enginerys does not host this file.
