This is a very good quality print (scan) of the original SONY service manual. The original from Sony is on very thin paper. Nevertheless it is very clear and sharp and excellent readable. I'm very satisfied to have now this rare document. I've looking for it many years (infrequent). It contains very detailed circuit diagrams, exploded views, part lists, PCB view with good readable connection lines. Very recommended.
 ;
A complete manual with all the needed details of calibrations and service instructions about the radio receiver.
A big deal.
Many thanks !

� Abnormal display
Is a waveform found in pins 2 to 4 of CR101 and pins 2 to 4 of CR102 and pins 2 to 4 of CR103 and pins 2 to 4 of CR104 ? Is pin 1 (VCC) of CR101 and pin 22 (VCC) of CR104 and pin 20 (GND) of CR101 and pin 1 (GND) of CR104 normal ? Check between IC401 and CR101. Yes Check around IC401. Is a waveform found in pins 33, 35 and 37 of IC401 ? No Yes No
Check the pattern and soldering of multi-link station PWB and LCD flexible PWB. If no problem is found, replace the LCD.
� Audio playback circuit
If playback time is counted but no sound is heard during continuous playback. Is an audio waveform found in pins 1 (TP721), 2 (TP722), 3 (TP723) and 4 (TP724) of J703 ? No Is there a pulse where duty varies in pins 2 and 5 of Q751, Q752, Q761 and Q762 ? No Is a pulse waveform found in pins 1, 4, 9 and 12 of IC751 and pins 1, 4, 9 and 12 of IC761 ? Are pins 2, 5, 10 and 13 of IC751 H ? Yes OK Does pulse waveform appear on pins 5, 6, 8 and 9 of IC203? No Check pins 68, 69, 71 and 72 of IC201 and pin 19 of IC401. If the voltage of pin 6 of Q751 and Q752 and pin 3 of Q761 and Q762 is below 2 V when setting VOLUME to MAX, check the power supply circuit of IC813 and IC821. Check soldering of J703, the remote control and the earphones. Yes
Yes
No
� The spindle motor does not rotate.
Does a waveform appear in pins 26 and 27 of IC201 after ending the test mode AUTO2 ? Yes
No
Check the periphery of IC201.
Is a waveform found in pins 60 to 64 of IC601 ? Yes If there is no defect in soldering of CN601 and insertion of the flexible PWB, replace the spindle motor.
No
