Up to now you are the BEST! Prompt-efficient and so reasonable ! I have been after SONY service manual for quite some time !Thank you very much ! I can recomend your service to
all my collegagues ! V.Bergfield .

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 !

NOTES:
Brief Introduction on the MPEG
1. When VCD source is selected the MPEG_RESET line will go positive triggering the following: - DRST pulse to reset 8-bit microcontroller IC 7212 RSTOUT# pulse to reset IC 7201 ES3880 IC7212 sends CD10_RST to reset Signal Processor IC 7802 on the CD Board.
2. Communication will establish as follows: DSA_ACK, DSA_STB and DSA_DAT between µProcessor IC 7401 on the Front Board and IC 7201 ES3880. DSA_STB to IC7204 ES3883 to select between NTSC (Lo) or PALS (Hi) DSA_A, DSA_D and DSA_S between IC 7201 ES3880 and microcontroller IC7212 SILD, SICL, RAB and SDA between microcontroller IC7212 and Signal Processor IC7802 on the CD Board.
3. Other activities between IC7201 ES3880 and Eprom IC7202, Dram IC7203 and IC7204 ES3883 will follows resulting in the OSD display on the TV set connected to the Video out socket. 4. When play button is activated the I2S signal (IIS_SCLK, IIS_WCLK and IIS_DATA) from the CD Board will enter IC7201 ES3880 which will work closely with the Eprom IC7202 and Dram IC7203. Inverter IC7205 74HC04D serves to reconstruct the Digital signal & level required by IC7201 ES3880. 5. Digital Audio information (AUDIOCLK, AUDATA and BCLK) will be send to DAC (Digital to Analog Converter) of IC7204 ES3883. 6. Analog output (AOL+, AOL-, AOR+ and AOR-) is amplified by the differential Op. Amplifier IC7207 NJM4560M. 7. Digital Video information YUV(0�.7) will be send to the Video processing part of IC7204 ES3883 and out to the Video out socket. 8. The HSYNC & VSYNC from IC7204 ES3883 to IC7201 ES3880 are to synchronize the Digital Video Information. 9. Mic Echo Input into IC7204 ES3883 is converted to digital signal (ARCLK, AIN and ARFS) for IC7201 ES3880 to combine into the Digital Audio Information.
