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.

I searched the Internet exhaustively for this manual and Owner-Manuals was the least expensive...but provided an excellent reproduction within 4 hours. Very satisified.
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.
