    9.Electronic Circuit Description 9.1 Main Board Circuit (1) Power Refer to circuit diagram sheet 7 of PWB-0452-03. The DC +12V output of AC adaptor is applied to the LCD-TV through P020. This supply is fed directly to P017#1、2 (Connector to Inverter). It also provide +9V for I009 (Audio Pre-Amp PT2314) and IT03 (MTS Decoder : TDA9850) through two regulators ( RC1117) I011 and I014 respectively.

  • Page 52: Circuit Diagram

    the I004( EEPROM) and the EDID data is written into the EEPROM in the factory during production. (3) AV Signal Refer to the page 8 in circuit diagram of PWB-0452-03. V17AFTWcan process 4 different Video signals. Includes Composite Video ( CVBS)、Separate Video(S-Video) and Component Video(YUV). Component Video also has Y Cb/Cr and Y Pb/Pr two types.

(C)CV( Y / Pb / Pr ): Signal enter from P011, P012, P014, Then enter Pin#43, 48, 54 of AD9883-110 pass by the matching impedance resister and capacitance.
  • Page 54 Refer to circuit diagrams Sheet 6 of PWB-0452. The signals of panel interface are all from I019 to the LCD Panel. The signal FPVCC (Pin#96 of I019) and MMTB3904( Q003) control the +5V power to the LCD Panel. The signals FPBACK and DVD0( Pin#95、62 of I019) are used for the control of backlight’s On/Off state and Panel luminance.
