A complete and well done copy of the manual, at a not expansive price!
The delivery of the manual is very fast.
Thank you for all

Perfect quality. Was able to fix speed drifting on my Sansui Turntable using the service manual instructions for PLL adjustment.
DESCRIPTION OF BLOCK DIAGRAM
1. Input Signal Part It is composed of three parts. -PC signal input part:15pin D-Sub and PC Audio input jack. -AV Video input part: RCA Jack(CVBS signal) -TV signla input part: TV Tuner input Connector(TV signal) 2. A/D Converter This block is composed of MST9883 (U5) and peripheral devices. MST9883 includes A/D converter, Pre-amp, and PLL. The basic RGB signal (0.7Vp-p) is input to R,G,B pin of MST9883(U5). Input video signal is amplified, Phase locking , A/D converts to 8bits digital signal by this IC(U4) and send the Digital video signal to EMH1(U9). 3. Digital Display Processor It is composed of EMH1(U9). It function that this IC(U9) converts desirable signal from AD Converter and Deinterlacer to operate LVDS part. 4. Deinterlacer This block is composed of MX88L284FC(U19) and peripheral devices. MTV230M(U15) controls this IC through IIC Line. And this IC convert 8 Bit Interlace Y/UV signal to Deinterlace signal. It output converted signal to Format Converter. 5. Panel-Link Circuit LVDS Transmitter (THC63LVD273, U2) is the IC that receives output digital signal of EMH1(U9) and output to LCD Module. 6. Micom Controller It is composed of MTV230MS(U15), its functions is controlling each IC, display mode and frequency through EEPROM and IIC comunication. 7. Inverter It functions that Input Power 12V converts 480Vrms to operate LCD lamp. 8. Video processor part. This block is composed of VPC3230D (U16) and peripheral devices. MTV230M(U15) controls this IC through IIC Line. This IC analyzes input signal of CVBS, Y/C and output analyzed signal (8bit interlace signal) to De-interlace block. Analyzed signal has video control signals like Contrast, Brightness, Sharpness, Color, tint signals Including Adaptive Comb Filter. 9. Audio processor part. This block is composed of MSP3410G (U7) and peripheral devices. MTV230M(U15) controls this IC through IIC Line. This IC analyzes Audio input signal through A/V Jack and PC audio. And output the analyzed signals to Audio Amplifier (TDA7268). 10. Audio Amplifier This block is composed of TDA7268 (U22) and peripheral devices. It amplifies audio signal input from Audio Decoder and output amplified audio signal to Speaker,Audio Output Jack. 11. Power part. It functions that Input power 12V converts TV-5V,AV5V,8VA and It functions that Input power 5V converts 2.5VD,2.5VA,3.3VS,3.3VD,3.3VA. 12. Control. It receives outer key input, transmits the input to Micom(U15). There is key input part and remocon receiver. 13. Teletext. It receives text information signal and displays text information through Text receiver Decorder. It called multi-text broadcast.
