The service manual when downloaded and printed out was clear and easy to read. I would have liked to have been able to enlarge some details, but this was not possible as the file permissions did not allow this. The service was very good. The time taken from placing my order to downloading the document was only a few minutes.
Perfect source of information for replacing the HDD and performing general diagnostics.

NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note on Schematic Diagram: � All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. � All resistors are in � and 1/4 W or less unless otherwise specified. � f : internal component. � 2 : nonflammable resistor. � C : panel designation. Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. � A : B+ Line. � Voltages and waveforms are dc with respect to ground under no-signal conditions. no mark : AUDIO ( ) : USB � Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. � Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. � Circled numbers refer to waveforms. � Signal path. F : AUDIO N : USB

Note on Printed Wiring Boards: � X : parts extracted from the component side. � Y : parts extracted from the conductor side. � f : internal component. � : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.) Caution: Pattern face side: (Conductor Side) Parts face side: (Component Side) Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated.
