The service manual is really great - thanks to it I was able to install the laser unit and thus "save" my CD-player, which seemed to be impossible before I had the manual.
Complete service manual in very good scanning quality with all schematic and PWB graphics as well as assembly & maintenance instructions. A slight drawback is that the rastering of the PWB graphics sometimes makes it a bit difficult to follow fine traces, but no showstopper.
