This manual was the factory original. Excellent value and contained all the details I needed. Easy dowwnload provided the information when I needed it.
 ;
Impeccable, document très complet. Perfect, i get all i need. All schematic are correct. Thanks

The manual is of better quality compared to other. I found it less expensive and therefore it it is the best buy cost vs quality.

I bought the service-manual of the sony ICB-1020(an old transmitter-receiver) at "www.Owners-Manual.com", I found the service-manual for a fairly cheap price(in comparison with other sellers). I filled in some questions, payed the order with Ideal, and within 24 hours I had my service manual. I was very happy:In no time I had my service-manual and everything, but literally everything was noted down in the manual; the electronic scheme, the parts list, etcetera.
A very practical, reference-document.

This comprehesive service maual was greatly appreciated, as was the digital download.
LC-Y# series working principle analysis
For the PAL system, when the RF signal is input to the tuner, the turner generates IF signal. Then the IF signal goes through the pre-amplifying circuit and 38M SAW, the VIF signal and 1ST_SIF signal will be generated. When these signals are input into the M52760E IC, the VIDEO_OUT and SIF signal will be generated. Then these two-way signals are sent to HEF4052BT, trapper and filter, which selective output signal according to different sound systems (PAL D/K, PAL B/G, PAL I). The audio signal returns toM52760E IC via filter to be decoded and then is sent to R2S15900, while the video signal is transferred to multi-system signal CVBS_TV via trapper and then is sent to FLI8125 directly. For the NTSC system, when the RF signal is input to the NTSC tuner, the turner generates IF signal. Then the IF signals goes through the pre-amplifying circuit and 45.75M SAW, the VIF signal and 1ST_SIF signal will be generated. When these signals are input into the M52760E IC, the VIDEO_OUT and SIF signal will be generated. Then the SIF signal is sent to MTS decoder LA72700 to perform BTSC stereo decoding, at last, the signal is input to R2S15900SP. The video signal is transferred to multi-system signal CVBS_TV via trapper and then is sent to FLI8125 directly. The AV, YPbPr/YCbCr, S-VHS and VGA signals from the input terminals, with the CVBS_TV signal, are sent to the main IC FLI8125, after decoding, filtering, De-Interlace, Adc and Scaler, and according to different panel, the main IC generates a 24-bit TTL signal or LVDS signal to send to the panel to recur the picture.
