VI. Circuit Princi le Analysis
1. Tuning program selection circuit:
The frequency synthesis phase-locked-loop ( LL) tunes the I2C bus to control the high
frequency head and some subassembly units. The tuning process is subject to control by

relevant pins of super single-chip TM A8899-XXXX. in 57 and in 58 of the micro-
processor (C U) input I2C bus tuning data to SCL and SDA pin of the high frequency
head.
The high frequency head of this device is frequency synthesis high frequency head, which
performs automatic frequency synthesis tuning based in the SCL and SDA bus data
output by in 57 and in 58 of the micro-processor. The 33V voltage of the high
frequency head is provided by +110V (21”)+130V (29”) via R518 voltage reduction and
N505 voltage regulation.
This frequency synthesis method is also known as phase-locked-loop ( LL) frequency
synthesis. The C U gives band switching signal under the control of the program
selection data provided by program reservation program, band switch and remote
control receiver, sets the frequency dividing ratio of the variable division frequency
divider in the LL according to the local frequency of the channel received; the variable
division frequency divider divides the local frequency from the high frequency head,
outputs the frequency and compares the frequency with the benchmark frequency; then
it adjusts the local frequency according to the difference to meet the local frequency
needed for various channels.
2. Image intermediate frequency circuit:
The intermediate frequency signal from the high frequency head is amplified by pre-
amplifier made up of V103 and others, enters the surface acoustic wave filter Z101
(F45C) and is filtered according to intermediate frequency characteristics and sent to
in 41 and in 42 of N101. The purpose of setting up the pre-amplifier is to compensate
the insertion loss of the surface acoustic wave filter and improve the signal to noise
ratio.
The intermediate frequency signal entering TM A8899-XXXX is amplified by the internal
pre-amplifier and video filtered, then IF detection signal (full TV signal) is output from
in 30, passes the emitter follower made up of the external R155, R156, V104 and
R158. Then it is coupled via C147 and returns to the selector switch in the TM A8873-
XXXX via in 26.
3. Audio processing circuit:

The second sound intermediate frequency signal SIF2 obtained via the internal phase-
locked decoding of TM A8899-XXXX passes the limiting amplifier and the frequency
discriminator to get an audio signal, which is output by in 28 and in 29. The two audio
signals are sent to in 6 and in 8 of N701 respectively for audio power amplification,
and the amplified audio signal is output to drive the speaker.
4. External AV input processing circuit:
The external audio and video 1 (V1, L1 and R1) are input from in 5, in 12 and in 2 of
N801 (TC4053) respectively; The external audio and video 2 (V2, L2 and R2) are input
from in 3, in 13 and in 1 of N801 (TC4053) respectively; The switching action of
N801 (TC4053) is controlled by control level output by in 56 of N103. After switching,
video is output by in 4 of N801 (TC4053) and input to TM A8899-XXXX via in 24 of
N103 for internal processing; audio is output by in 14 and in 15 of N801 (TC4053)
and input to TM A8899-XXXX via in 24 of N103 for internal processing.
5. Horizontal scanning circuit:
The main chip TM A8899-XXXX is separated internally in synchronization and consists
of VCO oscillation circuit, horizontal frequency dividing circuit, AFC circuit and horizontal
output driving circuit. The horizontal actuating signal is output from in 13 of TM A8873-
XXXX, amplified at driver stage via V431(2SC2383) and then amplified at output stage
via V432. T431 is a horizontal driving transformer, and C432, R433 and C433 are mainly
used to absorb the peak pulse on the electrode when V431 interrupts suddenly to
prevent V431 from breakdown. The horizontal tube V432 (2SC5296) is equipped with
delayed diode, so pay attention to substitution during maintenance. C435, C437 and
C436 are horizontal resonance capacitor, and VD435 and VD436 are delayed diodes. In
the case of horizontal wide, horizontal narrow and burning of horizontal pipe, such units
should be examined. L441 is a horizontal linear inductance and C441 is S corrective
capacitor.
T471 is a horizontal resonance transformer. The DC voltage of +110V (21”)+130V (29”)
is input from in 4 of T471. The horizontal resonance pulse output by in 8 is divided
into two lines: pulse on one line is directly supplied to filament of the kinescope to
provide 6.3V effective voltage; pulse on the other line passes R405 for voltage reduction

and VD408 (9.1V) for voltage regulation and is then sent to in 12 of TM A8899-XXXX
as the feedback pulse of the horizontal AFC pulse. The pulse output by in 10 of T471 is
rectified by VD447 and filtered by C447 to obtain +180V voltage, which is supplied to the
transmittal circuit as supply voltage. in 9 is kinescope electron beam circulating pin, i.e.
automatic brightness limit (ABL) pin, which supplies to in 27 of TM A8899-XXXX for
automatic adjustment limit of screen brightness.
6. Scanning circuit:
Field output stage circuit mainly consists of N451 integrated circuit and its peripheral
circuit. After synchronous separation, field synchronous signal is sent to field saw wave
formation circuit via field frequency dividing circuit; then field saw wave actuating signal
is output from in 16 of TM A8873-XXXX, sent to in 1 of N451 via R451, and output
from in 5 after internal actuating amplification and output power amplification, and
passes a field deflecting coil; vertical saw current flow through C457 and R459. C450,
R454, R453 and R461A/B are field feedback elements setup mainly in order to improve
field linearity and stabilize field circuit working points, and the field feedback signal is
sent to in 7 of LA7841. VD451 and C451 form a self voltage booster circuit, so that the
supply voltage of in 6 of N451 is 32V during forward field scanning period and is
boosted to 48V during backward field scanning period, so that the working efficiency of
field output stage is improved, and the supply voltage of in 7 during the backward field
scanning period is lower than the amplitude of field backward pulse of in 5, effectively
removing the backward retrace line. In addition, when the screen scanning is of poor
linearity, the fault usually occurs at the self voltage booster circuit.
7. rimary color exciting circuit:
The task of the primary color exciting circuit is to excite and amplify three primary color
signal and output RGB signal of around 130Vp-p and modulate RGB electron beam
current of the kinescope. rimary color exciting circuit usually includes white balance
adjustment function, which is mainly completed by I2C bus control.
RGB primary color signals are on V901, V911 and V921 base electrodes respectively and
amplified by the common emitter of the three tubes, and output by the collector and
directly coupled to V902, V912 and V922 for common base amplification. The

advantage of such common emitter --- common emitter connection is high working
frequency to achieve the purpose of broadband amplification. At last, V902, V912 and
V922 collectors output RGB signals of around 130Vp-p, which are directly coupled to
RGB cathodes of the kinescope via R917, R927 and R937 to control the size of RGB
electron beams.
