FAST very good and clear a great unexpensive job!!! very recomended for all people who are preofessional or hobbists as me!!!!!!
Thank you very much for this Service Manual, it helped us a lot to repair the M-4318!
...BUT: The parts list is missing and the free parts katalog on web isn't complete, so now we don't know the part numbers of the defect parts :(
We had to build them out of a working machine, and need the numbers to reorder the missing parts now.
Very good manual with clear electrical diagrams. Thanks owner-manuals.
Great manual, thank you, sony kp46s3 service manual perfectly, i am very happy.
Complete original Service Manual in good (scan) quality!

Joining terminal for crystal resonator (16.9344 MHz) Ground terminal for crystal oscillator. Make sure to ground. Output terminal for synchronizing signals of sub-code clock. Monitor terminal for 1 bit or 2 bit error correction Output terminal for sub-code P, Q, R, S, T, U or W. Output terminal for synchronizing signals of sub-code frame. When sub-code is stood by, falls. Input terminal for clock to read out sub-code. Schmitt input (when not used, make sure to ground.) Output terminal for synchronizing signal (7.35 kHz) which is divided from crystal oscillator. Output terminal for Q output standby of sub-code. Input terminal for read/write control. Schmitt input. Output terminal for Q output of sub-code. Input terminal for command from micro-computer. Input terminal either for clock to take in command input or for clock to take out sub-code from SQOUT. Schmitt inpu Input terminal for reseting this LSI. Switches to "L" position for a moment at power-on. Output terminal for test. Make sure to open circuit. (Normally "L" output) Output terminal of 16.9344 MHz Output terminal of 4.2336 MHz Input terminal for test. Pull-down resistor incorporated. Make sure to ground.
Input terminal for chip selecting. Pull-down resistor incorporated. Make sure to ground when not controlled.
Input terminal for test. No pull-down resistor. Make sure to ground.
Note: Each power terminal (VDD, VVDD, LVDD, RVDD and XVDD) must be supplyed with the same voltage.
