  • Page 7: Signal Process

    SIGNAL PROCESS The main chip is N201 TDA9363, AV control switch HEF4052, sound process chip is TDA9859, sound driver is N601 TDA7495S. The TV signal inputs into the tuner (U101) from CABLE or antenna. The pin 11 and pin 12 of the N502 are combined to select the band.

  • Page 8: The Horizontal And Vertical Circuit

    THE HORIZONTAL AND VERTICAL CIRCUIT Through Synchronous separating circuit, the video signal is divided into horizontal-Synchronizing signal and Vertical-Synchronizing signal. The horizontal-Sync pulse coming from the pin 33 is transferred to the horizontal-drive transistor, and will be used to drive the horizontal-transformer. The horizontal-switch transistor is V405, it and the +B supply drives the flyback transformer to generate the anode high voltage, the focus voltage, the screen voltage, the CRT board drive voltage 190V, the vertical drive voltage 17V and 54V.
