RF Section Tuner Tu101 receive the radio frequency signal, after inside circuit to do signal receiving, and signal amplifying. The amplified high frequency signal accompany with the high frequency oscillation voltage oscillated by set oscillator input to the mixer. The IF picture signal and sound signal formed in mixer and output from mixer, then send to picture IF processing circuit.
Page 31
Small Signal Processing Section Small signal processing section is the IF (intermediate frequency) signal across saw filter send in the pin12 and pin13 of IC201. The VIFIN signal through built-in PLL DEMOD, sound trap, video amplifier and synchronous detector processing, get the color video broadcast signal and 2 sound IF signal.
Page 32
(Fig3. Block Diagram of IC201.) Horizontal Scanning Section The horizontal drive signal send out from pin 56 of IC201, Q401 is horizontal driving transistor, coupled by horizontal driving transformer T402 , to control the horizontal output transistor working in switch on and off situation, get good linearly and enough amplitude of saw-tooth wave current to drive horizontal deflection yoke scanning.
Page 33
Vertical Scanning Section Vertical scanning section adopted STV8172A vertical deflection booster, we use as differential-output driver. The vertical raw-tooth wave signal sends out from pin14/15 of IC201 VDA/VDB. The two differential signal input pin 1 and 7 of STV8172A IC301. Pin2(+14v) and Pin7(-14v) of IC301 is power supply which come from the main power transformer.
Page 34
Audio Power Amplifying Section Power Supply Section AC supply 220V/110v through filtering network and rectifying circuit and get 300Vdc voltage. LF801/LF801A and CX802 makes up a differential mode rejection, LF802 and CY801,CY802 makes up a common mode rejection network. D801-D804 is rectifying network. 300Vdc voltage supply pin3 of T801, also through R804 send to pin8 of IC801 NCP1337.

STV8172A Application Hints Application Hints The yoke can be coupled either in AC or DC. DC-coupled Application When DC coupled (see Figure 4), the display vertical position can be adjusted with input bias. On the other hand, 2 supply sources (V and -V ) are required.

Page 58
STV8172A Application Hints AC-Coupled Applications In AC-coupled applications (See Figure 6), only one supply (V ) is needed. The vertical position of the scanning cannot be adjusted with input bias (for that purpose, usually some current is injected or sunk with a resistor in the low side of the yoke). Figure 6: AC-coupled Application Output (47 to 100µF)
Page 59
Application Hints STV8172A performs an integration of the parabolic signal on C , therefore the amount of S correction is set by the combination of C and C Application with Differential-output Drivers Certain driver ICs provide the ramp signal in differential form, as two current sources i and i with opposite variations.
