12.1Tuning circuitBuildup by frequency synthesized, PLL tuning, controlled by I2C bus tuner and some individual components. Tuning process controlled by correlation pins of UOC TMPA8873-XXXX. Pin57 & pin58 of CPU output I2C tuning data for SCL & SDA of tuner. FS tuner introduced in this chassis, cooperate with SCL & SDA data from pin57 & pin58 of N101, processing FS auto tuning. 33V for tuner supplied by 110V(130V), divided by R518 and stabilized voltage by N505.

Frequency synthesized fashion is also called PLL frequency synthesized fashion. It is the CPU controlled by channel subscribe programband switch and data from RC receiver and give the band switch signal. CPU set frequency divide ratio for variable frequency divider of PLL. Variable frequency divider dividing the local oscillation frequency from tuner and compare the phase with benchmark frequency, adjust local oscillation frequency accord with the local oscillation frequency needed by each chan-nel.

12.2. Picture IF circuitThe IF signal from tuner enter into SAW filter Z101(F45C) after amplified by Pre-Amp built up by V103 and so forth, filtered accordance with IF characte-ristic and enter TMPA8873-XXXX and output PIF demodulation signal(CVBS) from pin30, pass through the emitter follower buildup by R155R156V104R158, coupled to pin26 (inner switch)of TMPA8873-XXXX by C147.

Circuit Analysis

12.3. Sound processingThe SIF2, come from inner phase lock demodulate of TMPA8873-XXXX, turned into audio signal after limiting amplifier and frequency discriminator. Two audio signal, out of pin28 & pin29 of TMPA8873-XXXX, enter pin9 of N681 & N691 separated and audio power amplified. They are used to driver speakers separated after output from pin16 of N681 & N691.

12.4. Periphery AV input processingPeriphery AV1V1L1R1input from pin5pin 12pin 2 of N801TC4053separated. Periphery AV2V2L2R2input from pin3pin 13pin1 of N801TC4053separated. The level output from pin56 of N103 control the switch of N801. The video signal, output from pin4 of N801, transmitted to inner of TMPA8873-XXXX by pin24 of N103 after swit-ched. The audio signal, output from pin14 & pin15 of N801, transmitted to inner of TMPA8873-XXXX by pin24 of N103.

12. 5. Line scanInner synchronize separate included in TMPA8873-XXXX, build up by VCO surge circuit, line frequency divider, AFC circuit, line output driver. Line driver signal output from pin13 of TMPA8873-XXX, amplified by V431 (2SC2383) at line-excited level and then amplified by V432 at line output level.T471 is the FBT. Volts d.c. +110V21+135V29enter it through pin4. Line flyback pulse divided into two routes: one for heater (virtual value 6.3V) and one for FBP of AFC after through R405 and stabilized voltage by VD408 (9.1V). Pulse output from pin10 of T471 rectified by VD447 and filter by C447 and we get +180V for Pre-Amp as power supply. Pin9 of FBT is ABL , used as input of pin27 of TMPA8873-XXXX.

12.6. Field scanField output level buildup by CD78040/LA78041(N451) and its periphery components. Field synchronization signal enter into saw wave produce circuit after synchronization separate. Pin16 of TMPA8873-XXXX output field saw wave driver signal to pin1 of CD78040/LA78041by pass R451, and it is output from pin5 after driver amplified and output power amplified at the inner of CD78040/LA78041(N451). C450R454R453R461A/B are field feedback components for improving filed linearity and stabilizing the field

Circuit Analysis

work point. Field feedback signal enter pin7 of LA7841. VD451C451 buildup a bootstrap rise voltage circuit. The power supply for pin6 of LA7841 is 26V during scan time and bootstrap rise voltage to 48V during flyback time. In this way, the work efficiency of field output level is improved and also the voltage of power supply for pin7 will not less than the pulse amplitu-de of pin5 during flyback, and eliminate retrace efficiency accordingly. By the way, if the linearity of scan is not well, it is something wrong with boots-trap rise voltage circuit commonly.

12.7. H-PARAB emendation circuit:The principle of H-PARAB emendation is to using field parabolical wave to modulating amplitude of horizontal scan current. The current accretion according to parabolical wave rule during electron beam scan the middle of screen and so on the H-PARAB raster turned into rectangle raster.

12.8. Color driverTricolor signal amplified by tricolor driver. The white balance adjustment of this chassis completed under the control of I2C bus.

12.9. Power supply1A3 power supply: The power supply of this chassis adopt self-excitation

pulse transformer coupling switch power. Its very steady because of the photo-electricity transfer component adopted for stabilized voltage sam-pling.
