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.

DISASSEMBLY INSTRUCTIONS
INSTALLATION 1. Take care of the polarity of new IC and then install the new IC fitting on the printed circuit pattern. Then solder each lead on the diagonal positions of IC temporarily. (Refer to Fig. 4-5.) 4. When bridge-soldering between terminals and/or the soldering amount are not enough, resolder using a Thintip Soldering Iron. (Refer to Fig. 4-8.)

Confirm that no abnormality is found on the soldering position and installation position of the parts around the IC. If some abnormality is found, correct by resoldering. NOTE When the IC leads are bent during soldering and/or repairing, do not repair the bending of leads. If the bending of leads are repaired, the pattern may be damaged. So, always be sure to replace the IC in this case.
