* VCT4953: DRX+VSP+MSP+TVT. 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 including on-chip page memory.
* 2SC5936: Inputed H-DRIVE signal which comes from VCT4953.It amplify the H-DRIVE then output to Deflection Yoke.
* LA78045: Inputed VDP signal which comes from VCT4953.It amplify the VDP then output to Deflection Yoke.
* TDA7266SA/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.
* TDA6109JF: 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.
* STR W6750F: 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.
