13-2 Partial Block Description
13-2-1 System Board Block Description
* UOC TDA9377PS/N3/A.It contains the entire IF, audio, video, display and deflection processing for 4:3 and 16:9 50/60Hz mono
and stereo TV sets. The integrated microcontroller is supported by a powerful OSD generator with integrated Teletext and CC
acquisition
* ST2001HI: Inputed H-DRIVE signal which comes from TDA9377PS/N3/A.It amplify the H-DRIVE then output to Deflection Yoke.
* LA78045: Inputed VDP signal which comes from TDA9377PS/N3/A.It amplify the VDP then output to Deflection Yoke.
* TDA7297SA:It is a dual channel audio amplifier.The two audio signals L and R input to it and are amplified,
then output to speaker.
* 6107:It includes three video output amplifiers and is intended to drive the three cathodes of a color CRT directly. The output
R,G,B signals will connect to the CRT socket pins directly.
* EEPROM: As a extended ROM of TVT. It contains some data which is used to program executing.
* KA5Q0765RTH:SMPS control HIC. Provide switching signal in order to control the trans working.
* TDQ-6F/13F2S(TUNER):Receives the RF signal and output a fixed IF to Micom.
* Micom Block consists of five aspects as: Video & Sound IF Processor, Video Processor, Display and Deflection Processor and
Controller, OSD,Text Processing.
* TUNER-F/S;TDQ-6F/13F2S(tuner) : RF signal processing , Output IF signal
