Inverter circuit schematic diagram of Konka LC-TM2018 LCD TV (2)

Shown is the inverter circuit schematic diagram of Konka LC-TM2018 LCD TV .     In the circuit shown in Figure 2-71, the +12 V DC power supply is input from the ① and ② pins of CN1; the power-on and standby (ON/OFF) control signals are input from the CNI ③ pin: the adjustment control signal ADJ is input from the ④ pin of CN1 enter. The +12 V power supply provides the operating voltage for the drive circuit. In the circuit, the (D~@ pins of the pulse width signal generating integrated circuit Ul (BIT3106A) output control signals respectively. In the circuit shown in Figure 2-72, the control signal passes through the drive field effect tube circuit (U2A, U3A), high-voltage transformer (TIA, -12A, T3A) is boosted and turned into an AC high-voltage signal to power the backlight. Table 2-1 lists the pin functions of its core integrated circuit BIT3106A.
